Well, he's dead, so I don't think he pronounces it any particular way now.
But everyone, including newsreaders, politicians, and anyone else you will hear saying his name (or for that matter, the name of Brian Epstein, for example) pronounces it CORRECTLY.
And not, like Jeremy Corbyn did, in a completely exaggerated 'Jewified' bullshit way as yet another totally accidental event in the life of the most unlucky anti-racist of all time, the man who time and time and time again, finds himself accidentally laying wreaths to mourn the lives of terrorists who murdered innocent Jews, celebrating grossly antisemitic murals, cosying up to Holocaust deniers such as Paul Eisen, Stephen Sizer, praising blood libel promoters like Raed Salah, calling murderous Jew-haters his 'friends', saying that British Jews can't 'understand English irony despite living here all their lives', calling Jewish MPs 'the honourable member for Tel Aviv', embracing people who call for the death of Jews, writing hugely praising forewords for books that promote Holocaust denial and conspiracy theories about Jewish 'bankers', and so many more terribly unfortunate incidents that just seem to trip him up time, and time, and time, and time... again. What an unfortunate anti-racist he is.
