Michael Howard had his metaphorical purple, or should that be true blue, powder lined up and ready to chuck at the prime minister.

The first volley sailed right over the prime minister's head, disappearing somewhere into the no man's land of cross-party consensus (over Iraq sovereignty in this particular case).

The others hit their target fair and square - but bounced off and landed with an audible flop on the floor at the prime minister's feet.
The assault was all about Labour's record on Europe - and was part of the campaign leading up to the elections for the Brussels parliament in a couple of weeks' time.
And he failed to throw his final missile, using only five of his six allotted questions.
From his position a little further away Charles Kennedy took aim and flung his question about Iraq sovereignty - over its prisons in this case - but it too failed to raise much of a cloud.
Health Secretary John Reid, always nowadays apparently at the prime minister's shoulder, did not need to offer Mr Blair a supporting hand this time.
And the front bench remained entirely unrattled. Even MPs - now hardened after last week's events - were unmoved.
Howard agrred with Blair on Iraq
After the purple powder attack - which is really no joking matter - it was all rather dull, predictable electioneering.
So thank heavens for Labour backbencher, former minister and pro-fox hunter Kate Hoey.
She lobbed not dyed flour but the verbal equivalent of a brick. And it caught the PM just a glancing blow behind his left ear.
Why, she demanded, was he not meeting the Dalai Lama while he was in town. Was it because he had been told not to by the Chinese?
No it was not, said the prime minister. He had met the Dalai Lama before and would probably do so again one day.
Inevitably there were a few nervous glances up at the galleries from some MPs.
But, as Speaker Martin announced just before the session began, things have been tightened up since last week's attack.
Guests can pretty much only get in now if he has personally invited them.
The nervousness did not, needless to say, stop our brave administrators from attending the question time session in their usual numbers.
But with the local, mayoral and European parliament elections looming - and a week's recess just around the corner - things were both predictable and lacklustre in the extreme.
