Tulip Siddiq, the Economic Secretary to the Treasury and Labour MP for Hampstead and Highgate, is under investigation by the UK Parliament's standards watchdog for failing to promptly register rental income from a London property. This marks her as the first MP of the new Parliament to face such scrutiny, with the inquiry stemming from what her Labour Party described as an 'administrative oversight.' The property in question is valued over £100,000 and generates more than £10,000 in annual rental income. Siddiq has expressed her willingness to cooperate fully with the Parliamentary Commissioner on Standards. Meanwhile, investigations into three former MPs from the last Parliament remain ongoing, with over 100 investigations initiated during that period. The Standards Commissioner typically resolves such matters through rectification procedures for minor breaches.
