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.

Ed Miliband has already managed to steal a big pile of clothing from the Tories by pinching the One Nation tagline for his own party. But this weekend Chuka Umunna offered the beleaguered Labour leader another Tory tag that he might not be quite so keen on. Trying to defend the party, the Shadow Business Secretary said: 'The Shadow Cabinet and the leader of the Labour party are doing a huge amount already to sell Labour to the electorate which is why we've won back almost 2,000 councillors since Ed Miliband became leader of the party and of course as we move to the general election we will be turning up the volume even louder than it has already been in order to ensure that we form a majority at the next general election.' Oh dear.

Decca Aitkenhead has a history of producing revelatory August interviews that make tricky reading for the Labour leadership. Her 2008 interview with Alistair Darling involved the journalist following him around during the August recess and unleashed the 'forces of hell' against the then Chancellor when it was published. Her interview with Tom Watson in today's Guardian fits in with that tradition. Watson argues that there is no case for Unite to answer over Falkirk: Watson thinks on all three counts his party got it wrong. "I thought it was silly to report the allegations to the police, bordering on wasting police time." The whole affair, he insists, is "a storm in a teacup", since neither Murphy nor Unite did anything wrong.

Unless you're as optimistic as Jon Ashworth, it's pretty clear that messaging-wise, Labour have had a pretty bad summer. There are many reasons for this that many wise people have examined in quite some detail and at quite some length, but one of the major strategic errors is that the party appears to have made entirely the wrong assumption about what the Tories had planned for recess. Labour was clearly just lying in wait for more mistakes and bad news to come crawling out of the woodwork over the holidays. But they'd reckoned without the months of careful planning that the Conservatives had put into this slower season.
