The truth is that no one knows how old Titian was when he died, as the Encyclopedia Britannica states:
"The traditional date of Titian’s birth was long given as 1477, but today most critics favour the later date of 1488/90"
Meaning that when he died in 1576 he could have been anything from 86 to 99! Was Gordon Brown wrong? Possibly, but so was David Cameron. Unfortunately Cameron added to his ignorance by choosing to mock the Prime Minister when there are far more important issues in the world, and Cameron's woes have since been compounded by it being discovered that a member of the Conservative Party had changed the Wikipedia entry to fit their version of the facts.
Conservatives rewriting history! At least we don't have to rely on Wikipedia to remember how bad it was under the previous Conservative government!
