Old values are just out of date values. There is little point in Labour appealing to the working class as the party they are supposed to represent when those same people have been abandoning it for decades; in 1966 69% of manual workers voted labour, this was only 45% by 1987 [1] – long before Labour dropped its left wing ideology. Going back to core values if those core values are the values that the electorate wants.  [1] O’Neill, Brendan, ‘Labour lost the working-class vote a long time ago’, The Spectator, 12 May 2015,
