A second man has been charged with arson over fires at properties linked to Sir Keir Starmer.
Romanian national Stanislav Carpiuc, 26, from Romford, is accused of arson with intent to endanger life, the Metropolitan Police said.
He is accused of conspiring with Ukrainian Roman Lavrynovych, who appeared in court last week, and others unknown “to damage by fire property belonging to another, intending to damage the property, intending to endanger the life of another or being reckless as to whether the life of another would thereby be endangered”.
Carpiuc was arrested at Luton Airport on Saturday.
