Angela Rayner has been accused of a "shameless" waste of public money after allowing her lover to be ferried around by her bodyguards in her taxpayer-funded BMW.
Two close-protection officers said to cost tax payers thousands of pounds a day helped Sam Tarry moved bags and boxes in a BMW X5 between their two homes, the Mail on Sunday reported.
The highly trained security experts are employed to protect former Deputy Prime Minister Ms Rayner.
But she was nowhere to be seen as the bodyguards drove Mr Tarry and a series of boxes from her £800,000 seaside flat in Hove, East Sussex, to his £450,000 flat in Brighton around three miles away, the newspaper reported.
Ms Rayner's spokesman confirmed the protection officers helped Mr Tarry move "a small number" of the former Cabinet minister's possessions and said they may have decided to do so for security reasons.
But the former Housing Secretary now faces questions over why bodyguards on the public payroll were apparently being used to help with her domestic arrangements.
Furious Tory Party chairman Kevin Hollinrake said: “Once again, Labour has serious questions to answer.
“It is right that MPs and their families are protected from intimidation and violence.
“But Labour must now explain why Sam Tarry has been making use of Angela Rayner’s taxpayer-funded security and transport."
John O'Connell, chief executive of the TaxPayers' Alliance, added: "It's right that politicians in need of security are provided with it. But with that comes a responsibility not to abuse that system.
"Given the details of this story, it's clear there needs to be an investigation to check that no rules were broken".
Ms Rayner, 45, resigned from Keir Starmer's Cabinet last month after it was found she broke the Ministerial Code when she underpaid about £40,000 in stamp duty on the three-bedroom flat in Hove.
Despite no longer being a Government Minister, Ms Rayner has retained close protection officers because of the security risk she faces. Graffiti calling her a "tax evader" and a "b****" were scrawled on a wall outside her Hove property in the wake of the scandal.
A spokesman for Ms Rayner said: "Angela has a heightened and active security risk, and her property in Hove has been attacked with misogynistic and extremist graffiti.
"Mindful of the ongoing risks facing Angela, the security team facilitated her partner moving a small number of her possessions into a vehicle to minimise risk to her security.
"The close-protection team may undertake tasks based on the assessment of the situation and to ensure the safety and wellbeing of the person they are protecting."
A Commons spokesman said: "We do not comment on individual MPs' security arrangements".
