MP ANN Keen's job as health minister is under pressure after it emerged she claimed expenses for private health treatment.

Mrs Keen, who represents Brentford and Isleworth, charged the taxpayer £232 for an x-ray and consultation for one of her staff at the luxury Blackheath hospital in 2005.

The 25-year-old member of staff had been off sick and Mrs Keen charged the taxpayer for an assessment to see if they were fit to resume duties.

Labour MP Mrs Keen and husband Alan Keen, who represents neighbouring Feltham and Heston, hit the national headlines yesterday for claiming their empty Brentford property was their main home, as revealed by the Chronicle last week.

And now the Labour former chairman of the Standards Committee, Sir Alistair Graham, has called on the pair to be investigated for fraud by the police.

The former nurse has also come under fire for using £822.50 of taxpayers money to pay an accountant for tax advice and for claiming almost £10,000 for printing and delivering newsletters.

Andrew Dakers, who will stand against her for the Liberal Democrats next month, said: “For a junior health minister – and someone that has been a longstanding and vocal supporter of the NHS – to apparently be giving up on the NHS for treatment as these claims suggest, needs urgent explanation.”

Mrs Keen said: “This claim relates to a member of my staff who sustained an injury while at work. Following a period of agreed sickness absence, I requested an occupational health assessment for them to help them in resuming their duties.

“The Parliamentary Authorities agreed for these assessments to be paid for under the terms and conditions of my staff’s employment. The redactions in the released documents relate to patient confidentiality.”
