The party mandate was one labour should have looked at (I completely ignored it because muh turnout), for example losing the mayorship race in 2012, getting crushed in Scotland in 2012 losing the 2014 euro elections, almost losing a safe northern seat to UKIP despite virtually no media attention and average local elections showed that labour should have been doing more in the coasting years of 2012-2013
The only good set of locals for Labour was in 2012, right after the omnishambles budget.
Although every year, the collapse of the LibDems was the story and this disguised our own huge problems.
