Boris Johnson is set to make L700,000 on the sale of his one-time marital home. Real estate insiders claim he has received an offer on the house in Islington which is very close to its L3.75 million asking price. The five-bed townhouse was previously up for rent for L2,000-a-week. It has a private roof terrace with views over Regent's Canal, an open-plan kitchen and a palatial bathroom. Boris will have to split the windfall with his soon-to-be ex-wife Marina.
