Appearing before the Leveson inquiry, John Major has just denied that former Sun editor Kelvin MacKenzie ever uttered the famous words: "I've got a bucket of shit on my desk, prime minister, and I'm going to pour it all over you."
In his own appearance at the inquiry, MacKenzie told Robert Jay QC (see video, below) that the alleged exchange took place after Major phoned him following the UK's exit from the Exchange Rate Mechanism on "Black Wednesday" in 1992.
But his account was contradicted by Major, who said: "Perhaps my memory is very faulty indeed but I certainly don't recollect the same conversation that has been circulated".
"There are more myths about Black Wednesday than the Greeks ever created," he wryly added.
Both men were, of course, under oath, so who's telling the truth?
