A senior Treasury minister has referred herself to the ministerial standards watchdog after days of allegations that she has lived in multiple properties tied to the ousted Bangladeshi government, The Gurdian reports on Monday.

Tulip Siddiq, the City and anti-corruption minister, has asked Laurie Magnus, the prime minister’s independent adviser on ministerial standards, to investigate whether she might have broken the ministerial code.

Her request came after it was revealed that Siddiq had lived in multiple properties linked to her aunt Sheikh Hasina. Hasina recently resigned as Bangladesh’s prime minister after a popular uprising.

Siddiq wrote to Magnus: “In recent weeks I have been the subject of media reporting, much of it inaccurate, about my financial affairs and my family’s links to the former government of Bangladesh.

“I am clear that I have done nothing wrong. However, for the avoidance of doubt, I would like you to independently establish the facts about these matters.”

Labour officials said Siddiq would not travel with a Treasury delegation led by the chancellor, Rachel Reeves, to China this week as planned, and would instead “remain behind to assist with inquiries”.

Siddiq is under pressure over her occupancy of several properties, including a two-bedroom flat near King’s Cross and a separate home in Hampstead.

Siddiq’s connections to her aunt’s party have caused her political problems in the past, including in 2017, when she refused to answer questions about Ahmad bin Quasem, a British-trained barrister in prison in Bangladesh.

She insisted at the time she had nothing to do with her aunt’s government, saying: “I’m a Labour MP for Hampstead and Kilburn, I’m a British member of parliament.

“Be very careful. I’m not Bangladeshi and the person you are talking about, I have no idea about their case.”

Hasina was the world’s longest-serving female leader, but was criticised for crushing political dissent and twice fought elections that were boycotted by the main opposition party, the Bangladesh Nationalist party.

Last year she was forced to resign after widespread student-led protests against her government. Those protests, as well as the violent security response to them that Hasina oversaw, led to about 300 deaths.

Hasina fled the country she had led since 2009 by helicopter after protesters stormed her palace in the capital, Dhaka.

So far Siddiq has continued to enjoy Keir Starmer’s confidence even amid the revelations about her properties and links to senior figures in the Awami League.

Starmer said on Monday: “Tulip Siddiq has acted entirely properly by referring herself to the independent adviser, as she’s now done, and that’s why we brought in the new code.

“It’s to allow ministers to ask the adviser to establish the facts. And yes, I’ve got confidence in her, and that’s the process that will now be happening.”
