Holocaust denier David Irving has announced a speaking date in London, following a tour of the US.

His talk will take place at a secret location on May 21. The website reads: “You will be notified by email of the precise venue, a few days ahead of the date of the function.”

Previous dates include locations across the US, where Mr Irving is speaking on “"The Life and Death of Heinrich Himmler, Hitler's lieutenant. 44 years in 44 minutes". In Amsterdam, he will speak on "Hitler, Himmler, and the Final Solution. A Real History view, based on the archival documents.”

A spokesman for the CST said: “David Irving is a fairly irrelevant figure these days, but decent people should remain vigorously opposed to historical revisionism.”
