TORY ministers must make a “clear commitment” not to overturn a reinstated ban on bosses using temporary agency workers to break strikes, the TUC demanded today.

The widely criticised end to the long-standing ban — enacted in the dying days of former prime minister Boris Johnson’s scandal-hit administration last summer — was quashed as of today following a High Court ruling last month. 

Judges found that then business secretary Kwasi Kwarteng failed to consult unions as required by the Employment Agencies Act 1973 when making the draconian changes.
