The disgraced former Cabinet minister Chris Huhne was allegedly mocked by a prison officer on his first day at Wandsworth jail, the Sun reports.
According to the newspaper, the officer announced on the Tannoy system: "The right honourable member for Wandsworth North — down to the office".
Fellow inmates are said to have reacted with laughter as Mr Huhne left his cell to pick up his morning meal.
The newspaper also reported that the Justice Ministry declined to say whether an inquiry would be launched into the alleged incident.
Mr Huhne was sentenced to an eight month jailed sentence along with his ex-wife Vicky Pryce for perverting the course of justice over a speeding points scandal.
A Conservative MP is to ask the Attorney General Dominic Grieve to appeal against the "unduly lenient" eight month jail sentences for Chris Huhne and his ex-wife Vicky Pryce, according to The Sun's Whitehall correspondent, Emily Ashton:

Chris Huhne's van has arrived at Wandsworth Prison as the former Cabinet minister prepares to start his eight month sentence for perverting the course of justice.
Former Liberal Democrat leader Lord Ashdown has told ITV's The Agenda that although it was unlikely Chris Huhne, who was jailed for eight months today, would return to public life, it was not impossible.
He said: "I personally believe in redemption. You never say never in politics but if I ever said never about anything I'd say it about this. I don't think so.
"I don't say he can't ever comeback to public life provided that process of catharsis is gone through...my own view is that a period of silence rather than public statements might be a better course to follow but let's see what he says."

Carina Trimingham, the partner of Chris Huhne, was pictured leaving Southwark Crown Court today after the former Cabinet minister was sentenced to eight months in prison.
Asked about the jailing of former Cabinet colleague Chris Huhne, Prime Minister David Cameron said: "It's a reminder that no-one, however high and mighty, is out of the reach of the justice system."
Chris Huhne has apologised for the lies which led him to be jailed for eight months for perverting the course of justice.
The former Cabinet minister gave interviews to Channel 4 News and The Guardian hours before he was sentenced, where he said he felt "awful that people I love have been dragged into this gruelling experience".
The disgraced ex-MP told The Guardian: "I am sorry. I want to say that to family, to friends, to constituents and to colleagues, and more broadly to everybody who cares passionately about the causes I care about, including saving the planet for our children and our grandchildren."
And he admitted to Channel 4 News: "I certainly lied and lied again, and part of it was about saving my career but it was also partly to try and avoid the consequences for my family."
