The UK is marking the 50th anniversary of the death of Winston Churchill. He is regarded by many as the greatest Briton ever, but for some he remains an intensely controversial figure.

During Britain's darkest hours in World War Two, Churchill's leadership was vital in maintaining morale and leading the country to eventual victory over Nazi Germany.

In 2002 Churchill saw off the likes of Shakespeare, Darwin and Brunel to be voted the greatest ever Briton.

But in a career spanning some 70 years, he had more than a few moments of controversy.

"There's a danger in Churchill gaining a purely iconic status because that actually takes away from his humanity," says Allen Packwood, director of the Churchill Archives Centre.

"He is this incredibly complex, contradictory and larger-than-life human being and he wrestled with these contradictions during his lifetime."



Here are 10 of the most common debates that have raged about Churchill's legacy.

Views on race In April last year, Labour candidate Benjamin Whittingham tweeted that Churchill was "a racist and white supremacist".

Sir Nicholas Soames, Churchill's grandson, was outraged. And Whittingham's Conservative opponent Ben Wallace labelled the comments "ignorant" and "incredibly insulting". The tweet was deleted and the Labour Party said: "[It] does not represent the view of the Labour Party. He apologises unreservedly if it has caused any offence."

But there have previously been suggestions that Churchill held racist beliefs.

In 1937, he told the Palestine Royal Commission: "I do not admit for instance, that a great wrong has been done to the Red Indians of America or the black people of Australia. I do not admit that a wrong has been done to these people by the fact that a stronger race, a higher-grade race, a more worldly wise race to put it that way, has come in and taken their place."

Churchill certainly believed in racial hierarchies and eugenics, says John Charmley, author of Churchill: The End of Glory. In Churchill's view, white protestant Christians were at the top, above white Catholics, while Indians were higher than Africans, he adds. "Churchill saw himself and Britain as being the winners in a social Darwinian hierarchy."

"The mitigation would be that he wasn't particularly unique in having these views," says Richard Toye, author of Churchill's Empire, "even though there were many others who didn't hold them."

Soames thinks it is ludicrous to attack Churchill. "You're talking about one of the greatest men the world has ever seen, who was a child of the Edwardian age and spoke the language of [it]."

And Churchill's views on race were incomparable to Hitler's murderous interpretation of racial hierarchy, Toye says. "Although Churchill did think that white people were superior, that didn't mean he necessarily thought it was OK to treat non-white people in an inhumane way."

Poison gas Churchill has been criticised for advocating the use of chemical weapons - primarily against Kurds and Afghans.

"I cannot understand this squeamishness about the use of gas," he wrote in a memo during his role as minister for war and air in 1919.

"I am strongly in favour of using poisoned gas against uncivilised tribes," he continued.

These quotes have been used by critics such as Noam Chomsky to attack Churchill.

But the controversy is misplaced, says Warren Dokter, author of Winston Churchill and the Islamic World. "What he was proposing to use in Mesopotamia was lachrymatory gas, which is essentially tear gas, not mustard gas."

Churchill's 1919 memo continued: "The moral effect should be so good that the loss of life should be reduced to a minimum. It is not necessary to use only the most deadly gasses: gasses can be used which cause great inconvenience and would spread a lively terror and yet would leave no serious permanent effect on most of those affected."

In another memo about using gas against Afghans, Dokter says, Churchill questioned why a British soldier could be killed lying wounded on the ground while it was supposedly unfair "to fire a shell which makes the said native sneeze - it really is too silly".

But some still criticise the British air attacks used to quell rebellious tribes in the region.

And it's important to note that he was in favour of using mustard gas against Ottoman troops in WW1, says Dokter, although this was at a time when other nations were using it.

Bengal famine In 1943, India, then still a British possession, experienced a disastrous famine in the north-eastern region of Bengal - sparked by the Japanese occupation of Burma the year before.

At least three million people are believed to have died - and Churchill's actions, or lack thereof, have been the subject of criticism.

Madhusree Mukerjee, author of Churchill's Secret War, has said that despite refusing to meet India's need for wheat, he continued to insist that it exported rice to fuel the war effort.

"[The War Cabinet] ordered the build-up of a stockpile of wheat for feeding European civilians after they had been liberated. So 170,000 tons of Australian wheat bypassed starving India - destined not for consumption but for storage," she said upon release of the book in 2010.

Churchill even appeared to blame the Indians for the famine, claiming they "breed like rabbits".

"It's one of the worst blots on his record," says Toye. "It clearly is the case that it was difficult for people to get him to take the issue seriously."

"Churchill viewed it as a distraction," he explains. Preoccupied with battling Germany in Europe, Churchill didn't want to be bothered by it when people raised the issue.

"We have this image of Churchill being far-sighted and prophetic," says Charmley. "But what he does tragically in the case of the Bengal famine is show absolutely zero advance [since] the Irish famine 100 years earlier."

It was a horrendous event but it needs to be seen within the context of global war, says Packwood.

"Churchill is running a global war at this point and there are always going to be conflicting priorities and demands," he says. "It's an incredibly complex and evolving situation - and he's not always going to get everything right."

Arthur Herman, author of Gandhi & Churchill, has argued that without Churchill the famine would have been worse. Once he was fully aware of the famine's extent, "Churchill and his cabinet sought every way to alleviate the suffering without undermining the war effort", Herman wrote.

It was a failure of prioritisation, says Toye. It's true that Britain's resources were stretched, he says, but that's no excuse given the relatively small effort it would have taken to alleviate the problem.

Statements about Gandhi Churchill had strong views on the man now widely respected for his work in advocating self-determination for India.

"It is alarming and nauseating to see Mr Gandhi, a seditious Middle Temple lawyer, now posing as a fakir… striding half-naked up the steps of the Vice-regal Palace," Churchill said of his anti-colonialist adversary in 1931.

"Gandhi should not be released on the account of a mere threat of fasting," Churchill told the cabinet on another occasion. "We should be rid of a bad man and an enemy of the Empire if he died."

It's unfashionable today to question Gandhi's non-violent political tactics. He is venerated in much the same way as Churchill is in the UK. But for years he was a threat to Churchill's vision for the British Empire.

"He put himself at the head of a movement of irreconcilable imperialist romantics," wrote Boris Johnson in his recent biography of Churchill. "Die-hard defenders of the Raj and of the God-given right of every pink-jowled Englishman to sit on his veranda and… glory in the possession of India."

"Churchill was very much on the far right of British politics over India," says Charmley. "Even to most Conservatives, let alone Liberals and Labour, Churchill's views on India between 1929 and 1939 were quite abhorrent."

He was vociferous in his opposition to Gandhi, says Toye, and didn't want India to make any moves towards self-government to the extent of opposing his own party's leaders and being generally quite hostile to Hinduism.

Churchill's stance was very much that of a late Victorian imperialist, Charmley adds. "[Churchill] was terribly alarmed that giving the Indians home rule was going to lead to the downfall of the British Empire and the end of civilisation."

Younger Tories like Anthony Eden regarded Churchill with great mistrust during the 1930s because of his association with hard-line right-wingers in the party, he says.

"People sometimes question why on Earth did people not listen to Churchill's warnings about Hitler in the late 1930s," says Charmley, "to which the short answer is that he'd used exactly the same language about Gandhi in the early 1930s."

Attitudes towards Jews In 2012 there were objections to a proposed Churchill Centre in Jerusalem on the basis that he was "no stranger to the latent anti-Semitism of his generation and class".

Sir Martin Gilbert, Churchill's official biographer, countered that "he was familiar with the Zionist ideal and supported the idea of a Jewish state".

But being anti-Semitic and a Zionist are not incompatible, says Charmley.

"Churchill with no doubt at all was a fervent Zionist," he says, "a fervent believer in the right of the Jewish people to a state of their own and that state should be in what we then called Palestine."

But he also "shared the low-level casual anti-Semitism of his class and kind", he says. If we judged everyone of that era by the standards of 21st Century political correctness, they'd all be guilty, he notes. "It shouldn't blind us to the bigger picture."

A 1937 unpublished article - supposedly by Churchill - entitled "How the Jews Can Combat Persecution" was discovered in 2007. "It may be that, unwittingly, they are inviting persecution - that they have been partly responsible for the antagonism from which they suffer," it said. "There is the feeling that the Jew is an incorrigible alien, that his first loyalty will always be towards his own race."

But there was immediately a row over the article, with Churchill historians pointing out it was written by journalist Adam Marshall Diston and that it might not have represented Churchill's views at all accurately.

"Casual anti-Semitism was rampant," agrees Dokter, "[but] it's inconceivable to pitch him as anti-Semitic."

In a 1920 article, he wrote: "Some people like Jews and some do not; but no thoughtful man can doubt the fact that they are beyond all question the most formidable and the most remarkable race which has ever appeared in the world."
