Judith Alexander describes how Kentish Town house owned by the prime minister was targeted

The prime minister’s sister-in-law has said she feared what might have happened had she not woken up after her home was targeted in an arson attack, a court has heard.

The incident is one of a series of arson attacks that took place in May last year on property linked to Keir Starmer, which three men with links to Ukraine are accused of targeting. They deny all the charges.

Roman Lavrynovych, 22, and Petro Pochynok, 35, both from Ukraine, and Stanislav Carpiuc, 27, a Romanian national, appeared at the Old Bailey on the second day of their trial as jurors heard how Judith Alexander became aware of the fire in the early hours of 12 May last year.

“All of a sudden, I heard two bangs. It was very loud and sounded like two wheelie bins had been thrown at the door,” said a statement read to the court. “I did not see anyone on the street but when I looked down I saw smoke and an orange glow where the front door was.”
