Why didn't Boris Johnson update the Commons on the tensions between Iran and the US, instead of sending his Defence Secretary Ben Wallace to give a statement this afternoon? Jeremy Corbyn thought this was worth complaining about when he responded, telling the Chamber that the Prime Minister was 'hiding behind his Defence Secretary'. He demanded that Wallace explain 'where the Prime Minister is and what he is doing that is so much more important than addressing parliament on the assassination of Iranian General Qassem Suleimani’. Wallace's retort was that Johnson was 'running the country'. He also accused Corbyn of producing 'the usual tripe about "this is about Trump, this is about America",' which he described as being 'all the usual anti-imperialist guff'.

Despite the muttered predictions from some of the leadership campaigns, Labour's ruling National Executive Committee has today decided on a set of rules for its leadership contest that even a really committed conspiracy theorist would struggle to badge a 'stitch-up'. The timetable is very slightly longer – Jeremy Corbyn will remain Labour leader until 4 April when his successor is announced – and the rules on registered supporters applying to be able to vote are the same as in the 2016 contest. Candidates have a week to get enough nominations from MPs and MEPs (the threshold is 22).

The candidates to replace Jeremy Corbyn have been busily launching their campaigns and giving political interviews this weekend, with the party deciding the rules for the contest at a meeting of its ruling National Executive Committee tomorrow. There are still a couple of candidates left to launch their official campaigns, including Rebecca Long-Bailey, who appears to have disappeared to a location far more secretive than any prime ministerial holiday, and Ian Lavery. But here's what we know so far about each of the candidates: Keir Starmer: considered the frontrunner in the contest, the shadow Brexit secretary launched his campaign last night with a moving video.

Jess Phillips is expected to launch her bid for Labour leader this evening, having only said up to this point that she is seriously considering a bid to take over from Jeremy Corbyn. She is both the candidate most identified with the 'moderate' side of the party and the most high-profile, but that doesn't mean she is launching with a particularly well-formulated policy platform. In fact, while Phillips is well-known for her dislike of Corbyn and her altercation with Diane Abbott pretty early on as an MP, it's not quite as easy to work out what she thinks. Phillips has largely exerted her influence in Parliament in two ways. The first is as a campaigner on issues she knows a great deal about from her pre-parliamentary life, including domestic abuse and cuts to school funding.

If you wanted an illustration of the different emotional states of the two main parties, you could do a lot worse than to watch the humble address speeches just given by two Tory backbenchers in the Commons following the Queen’s Speech. While Tracey Crouch and Eddie Hughes cracked jokes and had their colleagues in stitches as if at a pantomime, the Labour benches looked as though they were about to go to a funeral. Many Labour MPs who managed to win their seats again are still in a state of numb, angry grief about the friends they lost and about what has happened to their party. The thought of laughing is just too much.

Boris Johnson and Jeremy Corbyn have just faced one another in the Commons for the first time in this new Parliament, though it is highly unlikely to be the last. The pair were responding to the election of the new Speaker, Lindsay Hoyle, and both chose to use their statements to make a few remarks about the election itself. Naturally, Johnson was greeted with a huge cheer from his MPs when he rose, and told the Speaker that 'I mean absolutely no disrespect to those who are no longer with us - but I think this Parliament is a vast improvement on its predecessor'. He then promised that 'this Parliament is not going to waste the time of the nation in deadlock and division and delay', and that on Friday MPs would vote on the Withdrawal Agreement Bill.

We won't see the full scope of what Boris Johnson plans to do for life after Brexit until the new year. There will be a few appointments this afternoon to replace gaps in the government, and then the Queen's Speech will introduce the legislative agenda on Thursday. But the full launch of the new government won't be until February. What we do know is that Johnson and his senior aide Dominic Cummings have got Whitehall in their sights, and are hoping to reshape government departments to make them work better. One of the biggest changes is carving up the Home Office so that it loses its responsibility for immigration and border security, with a new ministry carrying out that function.

Parliament returns tomorrow - without 47 of the people who were MPs just a few weeks ago. Some, like those standing as independents, had a pretty good hunch that they'd be booted out by the electorate on Thursday. Others had less notice, and realised only as the campaign wore on that their constituencies, many of which had been solidly Labour for decades, were turning away from them. Many of them will be in Westminster in the next few days to clear out their offices and make their staff redundant. You can usually tell the difference between a re-elected MP and one of their colleagues who lost as you watch them walk through the corridors of parliament.

Labour’s defeat is so terrible that it provides the kind of creative destruction that could save the party. It will be extremely difficult for the Corbynites to argue with much authority that one more push or slightly nicer newspapers would have got them over the line when the party hasn’t had a result this bad since 1935. But does the failure of Jeremy Corbyn necessarily mean that the ‘moderates’ in the party are going to be able to rescue it? In 2015, centre-left Labour MPs were confident that the members were so bruised by what they’d heard on the doorstep that they would happily elect a leader who took the party back to the middle ground of politics.

What's the point of political leaflets, anyway? Many voters in target seats will be asking that very question on an almost daily basis, as they shovel the latest snowdrifts of election literature into their recycling bin. We have social media, party election broadcasts and phone banks to reach voters. Who needs leaflets? There is a (I believe only half-serious) 'test' that some Liberal Democrat campaigners apply to the amount of information they think it is possible for a voter to absorb from a leaflet they're carrying from the letterbox to the bin. Given the parties keep sending them, particularly in those marginal seats where it's just not clear where the result is going to go, it's worth having a look at what they think is going to appeal to voters as they trudge once more to the bin.

John McDonnell was insisting this morning that Labour was going to win a majority, but just in case, insiders are suggesting that the Shadow Chancellor is planning to take over as interim leader if Jeremy Corbyn resigns after a general election defeat. McDonnell has long championed Rebecca Long-Bailey as a future leader, and there is speculation that he could install her as his shadow chancellor in order to boost her credentials. This explains why those around Corbyn were so keen to try to abolish Tom Watson as deputy leader in September. They tried to force a rule change at the party's ruling National Executive Committee meeting which would scrap the post.

Believe it or not, there was yet another televised election debate tonight, this time on Channel 4, called the 'Everything But Brexit' debate. The Tories had refused to take part, and while their decision will have been partly down to their ongoing battle with the broadcaster, which they have accused of being biased, they will also have viewed tonight's programme as an opportunity for them to make their central election pitch without even turning up. This debate worked in the Conservatives' favour because it was chaotic, with the representatives of the five parties who did turn up constantly talking and even shouting over each other and the presenter Cathy Newman. At times it sounded like a school playground at the end of term when everyone is tired, including the teacher.
