First day report
So, DC's first appearance at . What an extraordinary display of confidence the new boy gave - more so than Tony Blair when he first did it, as the shows. But the question some people will be asking themselves is was there too much confidence?
Clearly, telling Mr Blair that he had been the future once will go down as being the line of the day - and it's one David Cameron might find being repeated again and again in the coming years. Is this quite the thing to say on your first day in the job, some people will be asking, or does it show a touch of arrogance?
DC did try to live up to his promise to scrap the Punch and Judy show by pledging to back the PM on education. Tony Blair saw this promise of a new consensus coming - and that's why he too dropped the aggression - even to the point of refraining from jabbing his finger at the opposition benches (although he forgot on one occasion).
He even took off his glasses so that he could use them to gesture with instead of pointing. This is a trick Harold Wilson used, - he was given a pipe by early spin doctors to stop him gesturing aggressively (right). Tony Blair with a pipe... Now there's a thought.
Amid all the Tory euphoria, and the comparison with Tony Blair, DC will remember that he's in a very different situation from Mr Blair, who already had a hefty lead in the polls when he took over. Mr Cameron knows he is in far from that position.
