Tristram Hunt is not standing as Labour leader and will instead back Liz Kendall, he finally confirmed at the end of a long speech this morning. The party’s Shadow Education Secretary had some fun forcing hacks to listen to his assessment of Labour’s failure, which took a while, before he announced this, saying: ‘It is clear to me that I do not have sufficient support to be certain that I could run for the leadership myself.. there is a real risk that I might help restrict the choice for the party and that is not a risk that I am prepared to accept.' He complained that other candidates had been working on their campaigns for longer, saying they had 'longer, more established ambitions'.

There seems to be a checklist for Labour leadership hopefuls which all of them are very keen to tick off. When launching a campaign, a candidate must say that their party has just suffered a terrible defeat from which a number of profound lessons must be learned. These lessons all seem to be rather similar, and have led the candidates to say the following things: ‘We didn’t speak enough to aspirational voters’ Mary Creagh: ‘People felt that Labour didn't understand their aspiration to earn money and provide a better life for their family.’ Chuka Umunna (when he was standing): ‘We need to… focus on what is the new agenda that is going to get a Labour government elected in 2020.

As far as endorsements go, Andy Burnham is winning the Labour leadership contest hands down. He has managed to recruit Dan Jarvis - someone who has gained huge respect and admiration despite the fact no-one knows very much about him - as his latest backer. Jarvis tells the Mirror that Burnham ‘has the strength, experience and character needed to bring our party together and restore Labour’s connection with the British people’. Now, firstly this is a bit of a clue as to where Jarvis’s own politics lie: he’s a little more left wing than someone people who are caught up in his compelling back story may have noted.

It has been alleged that Nigel Farage never formally resigned from Ukip as part of what party sources have told the Spectator was a stitch up to avoid a leadership contest. It is claimed that the Ukip leader never wrote a letter to the party’s chairman tendering his resignation. He told the media on Friday that he would write to the party resigning. When it met on Monday, it is said the National Executive Committee had still not received a letter. A source tells me that when someone asked where the letter was, they were told ‘it is being typed out as we speak’. The source says the letter never appeared.

Tonight at midnight, something will change in Parliament. All the MPs who lost their seats in last week’s elections will have their passes cancelled, to be replaced by a pass giving them more limited access to the Parliamentary estate. They’ve been sneaking through Westminster over the past few days to clear out their offices and make their staff redundant. Some look eerily cheery as they do this. Others scuttle along, avoiding conversation. As the new intake of MPs look up excitedly at the ornate ceilings and take pictures of Big Ben on their phones, swelling a little with excitement and pride, the old MPs keep their eyes fixed firmly down on their shoes as they finish up in the Palace of Westminster.

The Labour party has decided on a medium-length campaign to elect its new leader, the Press Association reports, with the announcement on 12 September. This is slightly odd, given NEC members were still on their way to the meeting where they’ll vote on the timetable, but there you go. If that date is approved, it is a halfway house between the short campaign that some were arguing would stop the party from descending into lengthy navel-gazing while the Tories got away with introducing policies that weren’t properly scrutinised by the Opposition, and the long campaign that the unions wanted so they could sign up more members - and that some of the less well-known candidates wanted too in order to establish themselves.

Ukip is embroiled in an almighty row about money. It suddenly has too much of it, apparently. Guido reports that Douglas Carswell is refusing to take the full £650,000 of Short money that his party is entitled to for running a parliamentary operation that represents the four million votes the party won in the election. Ukip HQ are insisting he should have it, while Carswell is insisting they only take £350,000. HQ sources have been handing out some pretty heavy briefings about Carswell refusing to represent the party’s four million voters.
