Tulip Siddiq failed to declare income from a London rental flat for more than a year.

The Hampstead and Highgate MP registered the flat on March 4 this year, despite rental income starting on December 1, 2022.

All MPs are required to register interests within 28 days.

Siddiq, who was re-elected to Parliament representing the new constituency earlier this month, owns the flat with her husband, who collects the rent.

The flat has a value of more than £100,000 and is rented out for more than £10,000 a year.

The Daily Mail has reported that Siddiq apologised for the error, which has been blamed on an “administrative oversight”.

The MP, appointed Economic Secretary to the Treasury after Labour's general election victory, has also reportedly been referred to the Parliamentary Standards Commissioner over the breach.

Siddiq also earns income from another rental flat, which was registered in June 2015.

She has also registered gifts worth more than £1,700 since May 2023.

These include two box tickets worth £500 to see a Harry Styles concert at Wembley Stadium last June.

She was also gifted tickets for a concert at The O2 in April, as well as a Royal Shakespeare Company production of My Neighbour Totoro at the Barbican and the Chelsea Flower Show last year.  

Tulip Siddiq, London Labour and the Parliamentary Commissioner have been approached for comment.
