So, FTSE 100 company bosses have come out in favour of staying in the EU – even if, as Ed West notes, the 198 signatories in a letter to the Times represent only 36 companies. I wonder if anyone dropped out at the last moment to reduce the tally below the figure of 200. Of course big business supports the EU. It always has and always will. But who cares? What matters is what smaller, wealth-creating and job-creating businesses think. And they are much more Eurosceptic. A YouGov poll published in January revealed the huge divide between big business and the rest of the private sector on the issue. Out of 501 leaders of small and medium enterprises polled only 47 per cent favoured continued membership, with 42 per cent favouring withdrawal.

Although David Cameron insists that he wishes to remain on good terms with his Brexit-supporting Cabinet members, he's not planning to make life easy for them. Today Sir Jeremy Heywood, the Cabinet Secretary, has issued new guidance relating to the referendum that means SpAds and civil servants are banned from assisting Eurosceptic ministers with any material that could be used to back Brexit during office hours.

Over the weekend a number of Brexit activists walked out of an anti-EU Grassroots Out rally after George Galloway was revealed as the guest speaker. Although the Respect party leader was introduced by his new chum Nigel Farage at the event, even Ukip supporters voiced opposition to his involvement. So when Galloway appeared on today's Daily Politics, it wasn't out of the question that the presenter Jo Coburn might bring up the incident. Alas her attempt to ask him about whether his involvement could prove to a divisive issue fell flat, as Galloway took issue with her line of questioning. An excruciating exchange between the two followed: JC: But are you worried that you might be turning off some people who would like to support Grassroots Out?

George Osborne’s plan for this referendum was to turn it into a question of the future versus the past, for both the country and the Tory party. He wanted the voters to see the Out campaign as a bunch of people who wanted to take Britain back to a bygone era. Inside the Tory party, his aim was to have the talent and the ambition on the IN side with only old war horses and the passed over and bitter on the other side. But the events of the past 36 hours have blown this plan off course. Out now has one of the most popular politicians in the country on board in Boris, as well as one of the intellectual driving forces behind Tory modernisation and the party’s new social justice agenda in Gove.

At Cabinet this morning, every minister spoke in strict order of Cabinet seniority. This meant that Michael Gove was the first person to make the case for Out. I’m told that his argument to Cabinet was essentially the same as the hugely powerful statement he put out afterwards, which you can read in full here. The theme of the Cabinet discussion was, broadly, the trade-off between sovereignty and access to the free market. According to one of those present, where you fell on that question determined your position in the debate. One IN supporting Cabinet minister tells me that Oliver Letwin was the most persuasive speaker for that side of the argument.
