The Trade Union and Socialist Coalition (Tusc) vowed to nationalise banks and finance corporations yesterday during the launch of its election manifesto in Canary Wharf.

Standing right “in the belly of the beast,” leading members of the party announced its main policies, as well as the names of its 135 parliamentary candidates.

This year’s campaign is the largest in Tusc’s short history, as it is mounting a challenge in one in five of all constituencies across England, Wales and Scotland.
