Ken Clarke, Conservative MP: Public opinion has often been on the side of "some of the biggest blunders" in history, such as appeasement of dictator in the 1930s. Opinion polls can be "quite dangerous".

Ken Clarke, Conservative MP: You need a "sophisticated political debate" - and the nature of that debate has changed since he first entered parliament.

There has been a dramatic decline in membership of established political parties in Europe, with the fall greatest in the UK, as this graphic illustrates.

So how important is this apparent decision? Is it a major social moment? Page 3 is generating plenty of debate.

The Sun's apparent decision to cover up (slightly) its Page 3 models is also a subject for discussion.
