Foreign secretary Liz Truss will promise on Tuesday to bring in "tough and decisive action" to limit strike action by trade unions if she becomes Britain's next prime minister, the latest salvo in a divisive fight to lead the Conservative Party.
In a week when rail unions are planning to strike over pay freezes and job cuts, front-runner Truss said she would introduce a new law in her first 30 days that would guarantee a minimum level of service on "vital national infrastructure" and also raise the minimum threshold for trade union strike votes.
