Peter Riddell points out the differences between public and private sector voting intentions. Amongst private sector workers the Tories are at 45, Labour 29 and the Lib Dems 17. But with public sector workers it is Tories 38, Labour 26 and lib Dem 17.
It is not that surprising that support for the party of the centre-right is higher among private sector workers. But what is interesting is the Labour numbers which show that the party receives its highest level of support among the economically inactive (its overall figure, 30 percent, is higher than its numbers among either private or public sector workers) and that the party receives more support among private sector workers than public sector ones.
