I have always recommended that the Prime Minister treats everything from the Opposition as a joke.

The Prime Minister will recall meeting me and my hon. Friends the Members for Paisley and Renfrewshire, North (Jim Sheridan) and for East Lothian (Anne Moffat) to hear our arguments against the use of service charges and tips to pay the minimum wage. What are the Government going to do to end that scandalous practice, which is harming millions of people in this country?
