PRIME Minister Sir Keir Starmer faced increased calls today to replace Treasury minister Tulip Siddiq.

The parliamentary watchdog is investigating allegations about properties linked to her aunt’s political movement in Bangladesh.

Ms Siddiq referred herself to the independent adviser on ministerial standards Sir Laurie Magnus last Monday following reports that she lived in the properties in London linked to allies of her relative, former Bangladeshi prime minister Sheikh Hasina.

In a letter to Sir Laurie asking for an investigation to be opened, she maintained she had done nothing wrong.

Bangladeshi leader Muhammad Yunus called on her to apologise and resign.

He told the Sunday Times that London properties used by Ms Siddiq should be investigated and handed back to his government if they were acquired through “plain robbery,” adding: “She becomes the minister for anti-corruption and defends herself.

“Maybe you didn’t realise it, but now you realise it.”

Shadow chancellor Mel Stride also echoed Tory leader Kemi Badenoch calls for Sir Keir to sack Ms Siddiq, saying he needs to “get a grip” as it is now impossible for her to do her job.

He said: “Because she is the anti-corruption minister, she has serious charges laid against her now, or serious accusations around corruption, and it’s going to be really impossible for her to do that job under current circumstances.

“So she should step down, and the Prime Minister needs to get a grip of that.”

Sir Keir has previously stated that Ms Siddiq had “acted entirely properly” in referring herself to Sir Laurie and that he had confidence in her.

Ms Siddiq’s aunt was deposed in August last year following an uprising against her leadership and fled to India.

The former prime minister is facing an investigation by an anti-corruption commission in Bangladesh, with Ms Siddiq reportedly named as part of the case.

She was alleged to have been involved in brokering a 2013 deal with Russia for a nuclear power plant in Bangladesh in which large sums of cash are said to have been embezzled.

Ms Siddiq’s decision to refer herself to the ministerial standards watchdog came after the Sunday Times and Financial Times reported she had lived in properties linked to her aunt’s regime.

Cabinet minister Peter Kyle said that Sir Keir “will listen to what the authorities say.”
