Counter-terrorism police are investigating after two properties linked to Sir Keir Starmer were damaged in suspected arson attacks.
Emergency services were called to a fire at the prime minister’s private home in Kentish Town, north London, in the early hours of Monday.
There was damage to the property’s entrance but nobody was hurt, the Metropolitan Police said.
And just after 03:00 BST on Sunday, emergency services were called to a small fire at the front door of a house converted into flats in nearby Islington, a property that is also linked to Sir Keir.
One person was assisted to safety via an internal staircase by crews wearing breathing apparatus, London Fire Brigade said.
Police are also looking into a car fire as part of the probe.
All three fires are being treated as suspicious and inquiries are ongoing.
The prime minister – who lives at his official residence in Downing Street – is understood to still own the Kentish Town property which he lived at before the general election, but it has been rented out since then.
Sir Keir has thanked the emergency services for their work, his official spokesman said.
He added the matter was “subject to a live investigation so I can’t comment further”, and declined to provide any further details on who was in the property when the fire started.
Police earlier said that counter-terrorism officers were leading the probe “as a precaution and due to the property having previous connections with a high-profile public figure”.
