Gordon has developed a stutter. This is most unfortunate and his first performance at Prime Minister's questions was a little wobbly. But as Brown said himself, he has only been in the job for a few days. Oddly, David Cameron is by far the more experienced man at this set-piece event. The stutter, however, is not an asset.

It is refreshing that the two party leaders now clearly dislike each other so much. Cameron used to be tickled by Blair, but he sits poker-faced through Brown's responses. Although there was an attempt to be generous from the PM's side, this was not reciprocated and no one really thinks Gordon will be taking advice from the opposition.

Meanwhile, there are real changes in style with the new government. Where Blair was a sociable loner, Brown is the leader of a posse. When he enters the house, his trusted outriders sweep in with him. Ed Balls, the new Schools Secretary, of course, but Jack Straw also sticks very close. In Cabinet, Straw sits next to the Prime Minister and Alistair Darling sits opposite (these things are important).

Much of what we have seen this week was planned well in advance. Work on the new PM's policy agenda was well-advanced while he was still at the Treasury and officials were cleared by the Cabinet Secretary to work on this. Meanwhile, Jack Straw was already in negotiation with Justice department officials about constitutional reform, so insiders already knew what job he was heading for.

So what next? I am told there will be a blizzard of announcements through July and then the pace will slacken. Some think Brown should do almost nothing in August and just let the Tory discuss policy with themselves. This way they will simply tear each other apart. Simple, but brutal. This is what Gordon Brown is best at. But he must sort out that stutter.
