A FAR-LEFT Posties Union has lost an appeal against a ban against strikes.

The union was accused of trying to ‘block’ postal votes with the planned industrial action earlier this month.

Tory MP Andrea Leadsom lambasted the far-left militants and accused the posties of “holding the country to ransom.”

The union representing postal workers has lost an appeal against a High Court injunction blocking potential strikes by its members.

The Communication Workers Union (CWU) attempted to overturn an injunction granted to Royal Mail to block potential strikes related to a dispute over job security and employment terms.

Royal Mail had claimed that the vote for industrial action – supported by 97% on a 76% turnout – was invalid because members had been encouraged to open their voting papers at work before they were delivered to their homes.

The Court of Appeal dismissed the CWU’s appeal on Thursday afternoon, ruling that “the conduct of the union… had the effect of amounting to interference” with the voting process.
