Deputy Prime Minister Angela Rayner was last night facing questions over whether she is paying her own council tax surcharge on her second home.
'Two Homes' Rayner moved into her four-bedroom, grace-and-favour residence in Admiralty House in December - four months before her Local Government Department started levying an extra 100 per cent council tax charge on second homes.
Official records of MPs' expenses show that when she entered the Government, Ms Rayner designated her Ashton-under-Lyne constituency home as her 'primary residence', and her pre-Admiralty home - a rented London flat - as her second home.
That allowed her to claim back the £1,621 council tax bill on the London flat from the taxpayer as one of the housing costs reimbursed by Commons authorities.
But if she is still designating Ashton as her primary residence now, the £2,034 council tax bill for Admiralty House doubles to a whopping £4,068 if classed as a second home.
And, as a minister living in an official residence, she would have to pay both that and the £3,338 bill for the Ashton house herself - a total of £7,406.
Ashton does not attract a second-home premium because she has family members living there permanently, but questions have been raised as to whether or not she is paying the full £7,406.
Tory Shadow Minister Richard Holden asked the PM and the Chancellor if they were paying council tax on their Downing St flats as primary residences, and was informed that they were.
If she is still designating Ashton as her primary residence now, the £2,034 council tax bill for Admiralty House doubles to a whopping £4,068 if classed as a second home.
But on asking the same of Ms Rayner, he was stonewalled with: 'The Deputy Prime Minister's council tax responsibility is properly discharged.'
In a letter to Ms Rayner, Kevin Hollinrake, Shadow Secretary for Housing and Communities, asked if she had evaded the surcharge by 'flipping' her primary residence designation.
He said: 'If the minister in charge of council tax has dodged the super-tax by 'flipping', this raises serious concerns about the ethics and integrity of Labour ministers.'
She became known as 'Two Homes' Rayner after this newspaper revealed she shuttled between two council properties early in her marriage.
When her office was asked if she was paying a bill of £4,068 in London and £3,338 in her constituency, a source said: 'The administration of council tax for Admiralty House is for the Cabinet Office and Westminster Council, as has been the case for successive Secretaries of State.'
