The fall of Scottish Labour: How did it happen?

Following Labour's heavy defeat in Scotland at the general election, BBC Scotland Investigates has been speaking to former leaders, politicians and activists to examine how the party that was born in Scotland and helped shape the country came to have only one MP north of the border.

Knowing why it happened is one thing, but finding a way to reverse the party's decline is likely to be a greater challenge for whoever emerges as the new Labour leader.

Watch "BBC Scotland Investigates: The Fall of Scottish Labour" on BBC One Scotland at 21:00 on Monday, 22 June.
