Boris Johnson’s campaign to woo Tory MPs is continuing as the General Election approaches. I hear that he held another one of his suppers for colleagues at his home in the last fortnight, and that the MPs who did attend were seriously impressed. One says: ‘It was a really uplifting experience. I feel very conflicted between him and Theresa [May] as potential leaders.’ Another described the evening as ‘great fun, relaxed. He arrived with a rucksack clanking with booze and we had a takeaway curry and shot the breeze. No heavy canvassing.’ Number 10 is allowing these dinners, which involve a mix of MPs loyal to Cameron and rebels, to take place on the understanding that Boris does everything he can to help the Prime Minister get back into Number 10 on 7 May.

Nick Clegg has complained to Sir Jeremy Heywood, the Cabinet Secretary, that he was ignored before a government policy was announced, Coffee House has learned. The Deputy Prime Minister was annoyed that he did not get the chance to approve a change to the way Birmingham elects its councillors, from elections by thirds to all-out elections every four years. The change is part of reforms to the struggling local authority announced in a review by Sir Bob Kerslake. But Clegg claims he was never allowed to sign off the policy, which he should have seen because he chairs the government committee that approves most domestic policy - the Home Affairs Cabinet Committee. He complained to Sir Jeremy Heywood, who has told Clegg he is investigating, and to Eric Pickles.

If you want an illustration of just how damaging tribalism can be in politics, look no further than this Westminster Hall debate, held yesterday. Labour's Lisa Nandy had organised it, which was on ‘effects of government policy on UK poverty’, partly, it seems to raise some stories from her constituency about benefit sanctions that had been unfairly applied, and partly, presumably, to take a few party political pot shots at the Tories. That’s fair enough with an election coming up, and it would have been fair enough for the Tories in the debate to defend their record robustly. What doesn’t seem to be fair enough or indeed at all sensible is the response that Tory MP Mark Spencer offered to a specific case that Nandy listed.

Labour seems pretty keen to prolong its row with Boots chief Stefano Pessina. We're on day three now. After Boris Johnson weighed in on this on his LBC show, Chuka Umunna said ‘the Mayor of London is right to set himself apart from the Prime Minister and make it clear he finds it disappointing when firms do not join the overwhelming majority of British businesses in making a fair contribution to the Exchequer’. Party sources point out that when a senior businessman claims a Labour government would be a ‘catastrophe’ for Britain, it would be odd if the party just shrugged its shoulders. That’s why Labour is defending itself so robustly.

One interesting nugget from Lord Ashcroft’s latest batch of polling is what his focus groups in two seats - Sutton and Cheam, and Elmet and Rothwell - had to say about the parties’ messages. Here’s a quick summary: Conservative: ‘Finish the job and get back on track’. Labour: ‘Vote Labour to save the NHS’, possibly adding ‘and stop the cuts’ or ‘and tax the rich’. Liberal Democrat: ‘Vote Lib Dem to balance the extremes - to split the difference’. Ukip: ‘Leave the EU and control immigration.’ Greens: ‘Vote Green to save the planet.

The Tories are embarking on an ‘education week’, which means they won’t just be fighting Labour but also the Lib Dems, as the latter like to strike up a fight whenever something involving Michael Gove crops up. Indeed, some Tories suspect the Lib Dems in the Education department as being the source of today’s Independent on Sunday splash about Michael Gove continuing to meddle with education policy - though others point out that he’d probably receive most of them anyway through ministerial ‘write-rounds’ (more on this here).
