Divisions in Ayrshire, "the cradle of Labour"

Jim Murphy, the Scottish Labour leader, has described his party as the "underdog" in its battle against what he calls an "arrogant" Scottish National Party.

At the last election in 2010, Labour took 41 of the 59 Scottish seats, the Lib Dems 11, the SNP six, and the Conservatives just one Westminster MP.

But recent polls in Scotland have suggested that the SNP could take as many as 28 seats off of Labour.
