The Socialist Alliance gives a clear reply in its manifesto to the anti-European prejudice which Hague uses as the thin end of the wedge for racism. For workers' and socialist unity across Europe.
Socialists have no brief for either monetary system.
We do not mind whether the Queen's head or the euro symbol is on the coins and notes. The only answer to that is workers' unity across Europe. Workers who support either lobby gain nothing, but only lose political independence. Many things about it outrage the spirit even of classical liberal democracy, let alone socialism. Old national antagonisms have only been buried, not drained off.
