Disabled benefits: Tanni Grey-Thompson and Steve Webb

17 October 2012 Last updated at 13:17 BST

The paralympian and cross-bench peer Tanni Grey-Thompson tackled the Liberal Democrat work and pensions minister Steve Webb over government changes to benefits.

Baroness Grey-Thompson claimed thousands of people would be worse off, some by as much as £58 a week, when the new Universal Credit is introduced next year.

But minister Steve Webb told her the changes, which will be phased in over a number of years, would mean "spending more money overall", adding that the amount of cash disabled people get will be protected.

"If what you would get under the new one is less than what you're currently getting that cash amount is protected," he said.
