Highlights, not verbatim:
12.27pm: Ann Winterton asks the Prime Minister if he sees a contradiction between our soldiers fighting bravely in Iraq and Afghanistan for democracy and his opposition to a referendum? The PM replies by saying that the Commons is the place to decide matters of this kind.
12.11pm: Cameron asks about the SIX police investigations currently underway into the London Mayor's office. The PM says that it is not appropriate to comment on police investigations while they are still underway. Brown repeats the lie that Boris is planning to cut spending on the police and transport.
12.09pm: Clegg rises to loud cheers from the Tory and Labour benches. Why, he says, won't the Prime Minister join him in making the positive case for Europe by backing an in-out referendum. Brown responds by saying that you don't make the case for Europe by walking out of the Commons or abstaining in a momentous vote. He says that he will not go back to the 1970s with the LibDems on revisiting whether Britain should be part of the EU or not.
12.03pm: Cameron presses Brown again - why won't he answer? The Tory leader goes on to say that the Treaty gets rid of many vetoes and delivers an EU President among other things. Tony Blair is running for the Presidency of the United States of Europe. Brown responds by quoting Ken Clarke's opposition to a Treaty [Earlier on News 24 Clarke had dismissed a vote as "dangerous populism"]. Cameron responds by quoting Labour MPs in favour of a vote.
12.01pm: Cameron asks the PM if he thinks he'd win a referendum on the Lisbon Treaty if he held one. Brown responds by saying why he's not holding a referendum.
