Camilla Tominey pressed Shadow Chancellor Mel Stride on why the Conservative Government allowed foreign nationals to claim disability benefits during their 14 years in power, fuming, "you never stopped it".
The fierce exchange came as the Conservatives announced new proposals to restrict Personal Independence Payments (Pip) and Universal Credit health top-ups to British citizens only.
Under current rules, foreign nationals can claim these benefits, worth up to £1,200 monthly, if they have lived in Britain for two of the past three years.
Speaking on GB News, Camilla said: "There are many people watching and listening to this, Mel Stride, who might wonder: why on earth can foreigners claim disability benefits? And why did the Tories allow that to happen over the last 14 years?"
