How PM’s language changed

Saddam Hussein’s regime is developing weapons of mass destruction, and we cannot leave him doing so unchecked
April 10 2002, House of Commons

There are literally thousands of sites. I have no doubt that they will find the clearest possible evidence of Saddam’s weapons of mass destruction
June 4 2003, House of Commons

I don’t concede it at all that the intelligence at the time was wrong. I have absolutely no doubt at all that we will find evidence of weapons of mass destruction programmes
July 8 2003, evidence to Commons liaison committee

But I have to accept, as the months have passed, it seems increasingly clear that at the time of invasion, Saddam did not have stockpiles of chemical or biological weapons ready to deploy
