They were both receiving Disability Living Allowance after claiming they could barely walk unaided. Funmi claimed she had to hold onto the wall to stop herself falling while walking to her desk at Sandwell Hospital in West Bromwich, West Midlands.
She also claimed she had difficulty communicating and filling in forms – and even got her payouts increased by saying she needed constant care.
But she was caught when Department of Work and Pensions investigators spent four days secretly filming her walking to her car at the hospital in April.
Video footage showed Funmi walking to her vehicle in a disabled parking bay without any aids and no sign of a limp. Investigators then widened their probe to include daughter who was also picking up DLA payouts, who had claimed it took her 10 minutes to walk two yards.
Both women were arrested at the home they share in Wednesbury in August 2016. They maintained they were innocent of any benefit fraud.
But both were convicted of failing to report a change in circumstances after separate trials at Crown Court. Funmi who has worked for the NHS since 1995, is due to be sentenced on March 6. Daughter was sentenced to 34 weeks in jail, suspended for two years, on Wednesday.
Judge told her: “At some stage your mobility significantly increased and I am satisfied you knew that. Two work colleagues said they did not notice any restriction to your mobility.
