there are socialists who don't want to be in Europe ,same as tories or any other party. don't forget Maggie and john major started the descend as we know it by signing the Maastricht treaty and implementing it. as for immigration and economic migrants ,the british have been doing the same for centuries . the tories are coming out with there is less coming in, what they really mean there is less being counted as they sacked the staff who did the counting

remember some tories wanted the euro as well. some labour wanted it some didn't like Gordon brown

the Schengen Implementation Convention of 1990 , started the immigration and free movement and who was in power ye the tories
