Tony Blair took Prime Minister John Major to task at Prime Minister's Questions - this time, the subject was Europe and the single currency.
It was an issue which had long divided the Conservative party and which reached new heights during Mr Major's premiership.
Mr Major was taunted for failing to unite his party over Europe and impose a uniform message on Conservative candidates standing for election.
The attack came just weeks before the general election and was widely acclaimed as the moment that defined Mr Major as a man walking to defeat.
The prime minister hit back with a series of lukewarm responses but the damage had already been done.
