The failed EU referendum bill was a "bit of Valium designed to calm down" Eurosceptic Conservatives, a Labour peer has claimed.
Lord Lipsey said Labour had "choked up the Valium today" and David Cameron would have to think of something better to reconcile the pro and anti-European elements within the Conservatives.
The Labour peer added that the failed bill was a "complete mess" and could not become law unless it was changed to give the "British people a proper referendum at the right time".
