There are issues here, referred to in today's Sunday Times, quoted by the BBC.
"In a shot across the bows of ministers - who have used the Queen to promote the government's position on Scottish independence and the EU - a senior figure close to the Palace signalled last night that the royal household would resist any further efforts to drag her into politics," it says.
"The Palace will continue to fight a claim by the Sun newspaper that the Queen 'backs Brexit'. But officials have conceded that publicity about her private views on Europe is the consequence of the politicisation of the royals."
The paper says the intervention came as Justice Secretary Michael Gove apparently outed himself as one of the Sun's sources.
As political editor Tim Shipman puts it: "From the moment the Sun dropped on doormats on Wednesday morning, Buckingham Palace and Downing Street have been in damage limitation mode."
I think that's very wise. It looks as if the Palace spin doctors are preparing to put their hands up to the Sun accusation, in some form.
The Queen's attitude to the Scottish Indyref was pretty clear, and reports about it were not the cause of outrage to Cameron, because in that case they suited him. We also had the alleged "purring" episode when Cameron reported to her Majesty, seemingly to her satisfaction, that the UK had not yet fallen apart following that referendum.
