Here are the main points from the Number 10 lobby briefing.

• David Cameron is "relaxed" about the idea of publishing his tax return - but doesn't seem to have any plans to actually do so. This came up because in France a new rule is coming into force obliging ministers to publish details of their wealth. The prime minister's spokesman said that Cameron would be "content to publish his own arrangements and those of other ministers" and that he would be "relaxed" about this. Cameron first set out this view in 2012, after Boris Johnson published details of his tax returns in the London mayoral election. But the spokesman would not say that Cameron was committed to doing this, and he said nothing to suggest that Cameron is any closer to publishing ministerial tax returns than he was in 2012. The spokesman just kept coming back to the point about Cameron being "relaxed" about the idea. When a colleague asked if Cameron was "relaxed" about the idea of not publishing his tax returns, the spokesman sidestepped the question. Journalists left the briefing with the distinct impression that this will never happen - and also that being "relaxed" about something has become the latest political cliche to deploy when faced with a difficult question. ("Is the prime minister willing to give away all his money to a homelessness charity and live on the minimum wage for the rest of his life? He's very "relaxed" about the idea, they might tell us.)

UPDATE AT 2.37pm: Later a source indicated that journalists had come away from the briefing with the wrong impression, and that Cameron was committed to publishing details of his tax return at some point in the run-up to the 2015 general election.

• Cameron does not seem to support Labour's suggestion that there should be a review of the funeral arrangements for dead prime ministers after Lady Thatcher's funeral is over. Douglas Alexander, the shadow foreign secretary, suggested this yesterday and Ed Miliband's aides said it was a "very sensible" proposal. But, when the prime minster's spokesman was asked if this was a good idea, he replied: 'I don't think it's the right thing to make a commentary on the potential funeral arrangements for people who are still living." The spokesman also rejected suggestions that the arrangements for Lady Thatcher's funeral had been badly handled. The family, the current government and the previous government had all been involved, he said.

• Downing Street said it was up to the Commons authorities to decide whether to silence Big Ben for Lady Thatcher's funeral (as some Tory MPs are proposing). The spokesman would not say whether Cameron had a personal view.

• Number 10 dismissed a suggestion that PMQs should take place on Thursday to replace the session on Wednesday that is being cancelled because it clashes with Lady Thatcher's funeral. "The approach that has been agreed with the other parties is the one that should cause the minimum amount of disruption to the parliamentary schedule," the spokesman said.

• The spokesman rejected a claim that the response from foreign dignitaries invited to the funeral has been disappointing. (So far the only foreign prime minsters to confirm that they are coming are from Poland, Kuwait, Latvia, Italy and Canada, and the most high-profile American to confirm that he is coming is, so far, Newt Gingrich.) "You can see from the guests that have already confirmed their attendance, from the breadth of geographical representation - that says a very great deal about Lady Thatcher's global stature", the spokesman said.

• The spokesman said that Andrew Cooper, Cameron's director of strategy, was not leaving Number 10. Yesterday a report said he was going to leave. Today the spokesman said:

Andrew Cooper is staying in Downing Street. The prime minister thinks he does a very, very good job and he's a very important part of the prime minster's team.

• Downing Street rejected a claim (which has made the Daily Mail splash today) that the government is ignoring the interests of stay-at-home mothers. The government was bringing in measures to support all mums, the spokesman said. As examples, he cited more childcare for three and four-year-olds, the extension of this scheme to cover some two-year-olds and the single-tier pension.

• William Hague, the foreign secretary, is making a statement in the Commons at 3.30pm on the outcome of the G8 foreign ministers meeting.
