26 February 2012 Last updated at 14:30 GMT
A Liberal Democrat peer warned Conservatives that coalition plans to redraw seats in the House of Commons could be in trouble if they failed to back reforms of the House of Lords.
Lord Oakeshott handed Tory MP Philip Davies a copy of the coalition agreement to remind him of the deal which included changes in both houses.
Mr Davies said he was not elected on a coalition agreement and was not interested in turning the Lords into a "poor man's House of Commons" and accused the peer of a "petulant threat".
They spoke after a Sunday Politics films on reforms for the House of Lords.
