The government has yet to compose the motion that MPs will debate and vote on in tomorrow's Commons debate on Syria. And while some MPs are making clear that they are very nervous about the prospect of intervention, many others are yet to make up their minds. This means that as they return to Parliament today and tomorrow ahead of the debate (which starts at 2.30pm), they are sitting targets for the whips. There are some MPs like John Baron who are clear that they do not support intervention. Then there are a number of independently-minded MPs like Douglas Carswell and Sarah Wollaston who aren't worth much of a whip's time: it won't make any difference to how they cast their vote.

David Cameron, Nick Clegg and Ed Miliband this afternoon gave statements on Britain's response to the use of chemical weapons in Syria. There were important similarities between the statements which are worth examining. Here is what we learned: 1. The action must be legal. Miliband told the cameras after the meeting that 'when I saw the Prime Minister this afternoon I said to him that we the Labour party would consider supporting international action, but only on the basis that it was legal'. Meanwhile Clegg and Cameron both insisted that the measures being considered were legal. Clegg said: 'Any steps we will take will have to be legal. This Government, this Coalition Government, of course is not going to act outside the remit of international law'. 2. The action must be proportionate.

David Cameron and his colleagues have made fairly carefully-worded pledges on whether or not Parliament should be consulted if the government starts planning for a military intervention in Syria. They could feasibly stick to the precise wording of those pledges this week without recalling MPs for a debate, but this will be a very difficult position to maintain as pressure is growing on all sides for a recall. Labour's Shadow Foreign Secretary Douglas Alexander said this evening: 'If, in reality, the Prime Minister is now considering military options involving UK personnel then of course I would expect him to seek a recall of Parliament and to come to the House of Commons and make his case in advance of a decision being made.' It's not just the opposition pushing for a debate, though.

Labour could use HS2 as an opportunity to show voters that it is fiscally responsible by announcing that as the project's costs have spiralled out of control, it cannot back it. So runs the argument in favour of Ed Miliband dropping his party's support for the project. The party's transport shadow Maria Eagle has insisted today that high-speed rail remains a manifesto commitment for Labour, but Ed Balls has appeared on BBC News to drop what many are reading as some fairly heavy hints that his own support isn't quite so rock-solid.

MPs are currently in hiding in their constituencies from the silly season. But that doesn't mean they aren't encountering some rather silly behaviour themselves as they hold surgeries. Constituency surgeries are normally quite doleful affairs, with local people in dire straits turning to their MP for help with an impossible housing situation, a tangled immigration case, or a row with social services. Depending on the sort of MP you are, you either love your constituency casework so much that it's the main reason you're in Parliament, or you secretly think it a bit of a bore and long to return from a lengthy discussion about the bad smell from the local sewer (a favourite topic of angry local tweets from MPs of all leanings) to the safety of Westminster.

Opposition is underrated. You can spend your whole time pointing at Expensive Things and complaining that the Government Should Do Something about their cost, and grumbling about other things you don't like either, like a mother-in-law wearing a party rosette. What's not to like about being a professional complainer? The problem is that at some point you have to stop just pointing at things and complaining about them, and instead actually give a sense of what you would do instead. And if you've been too fussy to begin with, you end up disappointing people who thought you really were going to do something about everything you complained about to begin with. The Tories know this, and so are having a little bit of fun today with Liam Byrne's welfare speech.

If David Blunkett fancies being a kindly older mentor for the current Labour shadow cabinet, perhaps he could start by getting them all on television a little more, if only to say how great they think Ed Miliband is as party leader. As the summer has worn on and the Labour leader's troubles have thickened like a sauce, the shadow cabinet seems to have evaporated, according to this analysis of the last time any of them pitched up on the airwaves: · Maria Eagle appeared on BBC News (13 August 2013) · Caroline Flint appeared on Daybreak (9 August 2013). · Owen Smith appeared on the Today Programme (7 August 2013) · Sadiq Khan appeared on The World at One (1 August 2013) and the Andrew Marr Show (28 July 2013).

Caroline Lucas' arrest this afternoon at the Balcombe fracking protest might be quite useful for the Green MP, but it's hardly going to give ministers a sleepless night. Lucas' presence is actually rather distracting from a real problem that ministers do need to address: ensuring that communities feel they have a stake in the shale gas exploitation taking place on their doorstep. David Cameron rather got their hopes up recently when he, by a slip of the tongue, promised that communities would get a £1 million incentive for accepting drilling on site when the figure was actually £100,000.
