The trend on heres seems to be more or less intentions of voting labour with UKIP being an alternative or maybe a protest vote (taking into account local politics)..Labour are ahead in National polls but that is usual in a half term government.. to me the Tories will get the hardcore 35-37% they always have.. Lib-Dems no more than 14% and UKIP could get around 9%..but that does not give UKIP many seats in a General Election.
Once again it will be a two horse race.. Mr Ed Milliband will not win that race.. if labour go into the next Election with Ed at the helm they will not gain a majority.
In case there's any interest here's a site updated regular by the latest national polls
