Heidi Alexander has been appointed the new transport secretary after Louise Haigh stepped down.

The Swindon South MP had been serving as a justice minister until her promotion today, and worked as Sadiq Khan’s deputy transport mayor between 2018-2021.

Ms Haigh resigned after Sky News revealed she pleaded guilty to an offence related to incorrectly telling police that a work mobile phone was stolen in 2013.

In a letter to the prime minister, she described the incident as a “mistake” but said that “whatever the facts of the matter, this issue will inevitably be a distraction from delivering on the work of this government”.

Ms Haigh claims she was “mugged on a night out” and believed her phone had been stolen, but discovered “some time later” this was not the case.

She called the incident a “genuine mistake from which I did not make any gain”.

The Tories have said it raises questions about what exactly Sir Keir knew when he appointed her to his shadow cabinet in opposition.

Responding to her resignation letter, the prime minister thanked Ms Haigh for “all you have done to deliver this government’s ambitious transport agenda” and said: “I know you still have a huge contribution to make in the future.”
