Did Brown Lie to Inquiry?

clipped from www.telegraph.co.uk Lord Guthrie: Gordon Brown did not give all we asked for Long before we went into Iraq or Afghanistan Gordon Brown was unsympathetic to the defence budget when he was chancellor. The whole defence budget was extremely difficult to run in Mr Brown's time, says Lord Guthrie Photo: Peter MacDiarmid The Ministry of Defence received the bare minimum from the chancellor, who wanted to give the military as little as he could get away with.

The one fact that this Chilcot inquiry seems miles away from (I am loath to say avoided) was if Chancellor Brown paid for every request from the MOD, did the MOD spending increase by not a penny? In fact, during a period of so-called war, there was a reduction in expenditure.
Will someone explain, in simple English, how?
