Boris Johnson has struck a deal with publisher HarperCollins to write a memoir which editorial sources say will earn him over £6million.

< p>No date has yet been set for the book's release, with the announcement coming only months after Mr Johnson was forced out of office and amid ongoing speculation he may have the ambition to return to frontline politics.

His wife Carrie Johnson is also believed to be writing a book.

Arabella Pike, publishing director at William Collins of HarperCollins, has promised a memoir from the Prime Minister "not like the others".

She said: "I look forward to working with Boris Johnson as he writes his account of his tenure at some of the most momentous events the UK has seen in recent times.

The disgraced former prime minister's fees are undisclosed, but publishing insiders have suggested he could be paid upwards of £6million.

Other prime ministers who wrote memoirs reportedly earned a whopping six-figure sum for their contracts.

Tony Blair reportedly earned £4.6million for his memoirs A Journey, while David Cameron reportedly won £1.5m for his memoir, For The Record.

Margaret Thatcher reportedly received £3.5m pounds for a two-pound deal after leaving office in 1990. Like Mr Johnson and Mr Cameron decades later, the Iron Lady also signed with HarperCollins, app ment at the request of owner Rupert Murdoch, the newspaper magnate who allegedly had a close relationship with the Prime Minister in the 1980s.

Johnson joins a line of former prime ministers who wrote memoirs following their tenure

This week the former prime minister was asked to come clean about his financial affairs and end his Tory leadership ambitions, as the former prime minister found himself embroiled in a fresh row over money.

The prime minister is believed to have secured an £800,000 line of credit while at No 10, backed by a millionaire relative who was suggested for a leading role at a quango.

A source told the Sunday Times that Mr Johnson had been on the verge of 'going bankrupt', and the line of credit would have been made available for his expenses of s subsistence, including divorce payments.
