Tulip Siddiq, the Labour MP for Hampstead and Highgate in north London and the Economic Secretary to the Treasury, is under investigation by the Parliamentary Standards Commissioner for not registering rental income from a London property on time. This makes her the first MP of the new Parliament to face such an investigation. Three former MPs are also under investigation for various breaches, including ex-Conservative MP Bob Stewart, former Reclaim MP Andrew Bridgen, and former Tory Sir Conor Burns.
