I was looking at some Bills on the Parliament website, and I wanted to find out more info about what some of the stages abbreviations meant. So I clicked on the link to take me to this page. And I was delighted to learn that 'ping pong' is a proper term, when discussing the progress of legislation through Parliament. PP - Ping Pong, where the bill passes back and forth between the two Houses debating amendments to the bill L - Commons' Amendments considered in the House of Lords C - Lords' Amendments considered in the House of Commons Brilliant -the mental images of members of the House of Lords and House of Commons playing Ping Pong in Parliament will keep me amused all day!! :-) Off to have flashbacks to Pong now!
