Berliner Tageszeitung - Ultra-rich UK PM to move into Downing Street flat

Sunak's portfolio of properties reportedly includes a penthouse in California, a house in London's exclusive Kensington district and a mansion in his Yorkshire constituency in the north of England.

But the prime minister's press secretary has confirmed he will be moving into Downing Street.

"They will be moving into the No 10 flat," the spokeswoman said, adding that she did not know if they had any plans to redecorate.

Former leader Boris Johnson got into hot water over an expensive refit of his prime ministerial flat believed to have cost more than £200,000 ($230,000).

The ousted premier's lavish refurbishment of his flat, next door at number 11 Downing Street, was overseen by his wife Carrie. Controversy over the way it was funded handed ample ammunition to Johnson's critics.

The details of expensive rolls of wallpaper, hyper-fashionable soft furnishings and deep-pocketed donors became the stuff of endless newspaper articles that ultimately undermined his authority.

Although the number 10 flat in Downing Street is in a prime location, it is relatively small.

Sunak's move there will mark a return to the flat being the London home of the British prime minister.

Traditionally British leaders lived in the flat above number 10 Downing Street. The main building it sits above is the official residence and office of the country's prime ministers.

Chancellors generally lived in the larger flat above number 11.

However, when Tony Blair and Gordon Brown were prime minister and chancellor, they swapped flats to accommodate Blair's growing family.

In fact, Sunak only recently moved out of the number 10 flat as he lived there during his time as Johnson's finance minister, until resigning in July.

Asked why he had chosen to live at number 10 and not the bigger number 11 flat, the spokeswoman said: "They were very happy there."

The Sunaks, who have two daughters and a Labrador dog, however, are unlikely to need to rely on rich backers for any flat redecorations.

Before marrying the daughter of an Indian billionaire in 2009, Sunak worked at Goldman Sachs investment management company and two hedge funds,

His wife Akshata Murty owns a substantial stake in her father's Infosys software company.

Together, the couple are on The Sunday Times rich list, with a net worth of £730 million.

British prime ministers have been based at 10 Downing Street since 1735 with previous residents living behind its famous black door including Benjamin Disraeli, William Gladstone, Winston Churchill and Margaret Thatcher.

The building is much bigger than it appears as it is linked to another property behind and has also taken over much of number 12.

Prime ministers also have the use of a country residence, Chequers.
