Grangemouth: Another provocation
A chorus of condemnation has greeted David Cameron's launch of an inquiry into trade union tactics in the wake of the Grangemouth affair.
Unite the Union has described it as a Tory election stunt and rightly called for a refusal to cooperate with it.
Frances O'Grady of the TUC said that it is "simply part of the Conservative Party's general election campaign" and even SNP leader Alex Salmond has suggested that it "was entirely about seeking electoral advantage". These responses are fine as far as they go.
