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”.
On the Kentish Town property fire, London Fire Brigade (LFB) said it had been called to a “small fire” at 01:11 BST on Monday that was under control about 20 minutes later.
It said about 10 firefighters and two fire appliances from Kentish Town Fire Station attended the incident.

A Metropolitan Police statement said: “Officers attended the scene. Damage was caused to the property’s entrance, nobody was hurt.
“The fire is being investigated and cordons remain in place while enquiries continue.”
It later emerged that just before 03:00 on Thursday, firefighters were called to a small car fire on the same street. The fire was brought under control by 03:30.
At just after 03:00 on Sunday, firefighters were called to the Islington fire.
The Kentish Town house has previously been targeted by protesters. Last year, three people were found guilty of public order offences after staging a pro-Palestinian demonstration outside it.
On Monday afternoon, investigators could still be seen outside the property with local residents being allowed through the tape as they returned home from work.
