MPs 'should cancel hols'.
The Liberal Democrat leader insisted Parliament should not be allowed to go into recess until "every nook and cranny" of the political system was reformed.
Mr Clegg set out a 100-day action plan to clean up Commons expenses and speed up key constitutional changes.
"Let us bar the gates of Westminster and stop MPs leaving for their summer holidays until this crisis has been sorted out, and every nook and cranny of our political system reformed," Mr Clegg said.
"I'm setting out a plan of action to get all the changes we need delivered in just 100 days."
