Counterterror police are investigating a fire that broke out in the early hours of Monday morning at a north London home owned and rented out to tenants by Britain’s prime minister, Keir Starmer.

After winning last year’s general election, Mr. Starmer moved into the prime ministerial residence at 10 Downing Street and, according to official records, leased his four bedroom family home in Kentish Town.

“On Monday, 12 May at 01:35 hrs., police were alerted by the London Fire Brigade to reports of a fire at a residential address,” London’s Metropolitan Police said in a statement.
