Take That star Gary Barlow has been urged to hand back his OBE after a tribunal ruled he had invested in a scheme set up to avoid paying millions of pounds of tax.
The chair of the Public Accounts Committee said Labour's Margaret Hodge said Barlow "might want to show a bit of contrition by giving back his OBE".
Conservative MP Charlie Elphicke agreed, telling The Times: "People who have seriously abused the tax system should be stripped of their honours."
Barlow, who led plans for the Queen's Diamond Jubilee concert, was given an honour for services to the entertainment industry and to charity in 2012.
