Labour frontbencher Tulip Siddiq is coming under increasing pressure over her links to her aunt and ousted Bangladeshi leader Sheikh Hasina. Ms Siddiq has denied any wrongdoing and referred herself for an investigation.
Anti-corruption minister Tulip Siddiq could lose her job if the investigation into her properties finds she broke government rules, a cabinet member has suggested.
Science Secretary Peter Kyle was asked about Ms Siddiq on Sunday Morning with Trevor Phillips.
She has referred herself to the prime minister’s independent adviser on ministers’ interests, Sir Laurie Magnus, following reports she lived in properties in London linked to allies of her aunt, Sheikh Hasina, the deposed prime minister of Bangladesh.
There have also been questions about trips she took to Russia alongside her aunt.
Ms Siddiq insists she has "done nothing wrong".
As economic secretary to the Treasury, Ms Siddiq oversees anti-corruption efforts in the financial sector as part of her brief.
Mr Kyle told Sky News: "With Tulip, she’s referred herself straight away to this.
"There is a process under way and we know full well it will be a functional process, and the outcomes of it will be stuck to by the prime minister and this government, a complete contrast to what we’ve had in the past."
He gave this answer after Trevor pointed out Labour would have been calling for a sacking if the roles were reversed and the Tories were in power.
Mr Kyle contrasted his party’s stance with the Conservative one - saying he called for an investigation into allegations of bullying from Priti Patel, and she "had to be dragged to that inquiry".
He added that he let the inquiry pan out.
"The results came out, she was found guilty, and no action happened," Mr Kyle said.
His response came after Conservative leader Kemi Badenoch called for Ms Siddiq to be sacked yesterday.
Shadow chancellor Mel Stride repeated the calls today to Sky News.
He said: "What is not right is that the prime minister is not moving her out of that position and getting her to step down
"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."
