Sarah Brown to write Downing Street memoirs
Sarah Brown has agreed to write a memoir of her three years living in Downing Street, she has revealed.
The wife of former PM Gordon Brown has struck a deal with the publisher Ebury, with the book having a working title of Behind the Black Door.
Writing on Twitter, she said she would be "chained to a laptop from Monday".
Mrs Brown, a former public relations executive, kept a fairly low public profile until she joined her husband on the campaign for the general election.
She and her family left Downing Street last month, when Labour conceded power to the Conservative-Liberal Democrat coalition.
Mrs Brown's memoirs follow those of previous Prime Minister Tony Blair's wife Cherie, which were published in 2008.
On Twitter, she says she "has just agreed with my publisher Ebury to write a book - working title Behind the Black Door - so chained to laptop from Monday morning".
Meanwhile, acting Labour leader Harriet Harman has revealed that Mr Brown, who is staying on as MP for Kirkcaldy and Cowdenbeath, should return to politics soon.
She told BBC One's Andrew Marr Show: "He's certainly going to be coming back over the next few weeks to the House of Commons.
"He's been reorganising the arrangements for his family."
Ms Harman added: "He was elected as a Labour MP and has a strong sense of duty to that."
