Gang of Four: Could the Labour Party split again?
It's the 35th anniversary this month of the Limehouse Declaration that led to the founding of the Social Democratic Party (SDP).
Back in 1981, the so-called "Gang of Four" senior Labour politicians broke off - partly in protest at the leftward drift of their party.
Could history repeat itself? Very possibly, according to two surviving members of the Gang of Four - Shirley Williams and David Owen. They spoke to BBC Newsnight's Lewis Goodall as part of a look back at that landmark moment.
