PCS union says more than 250 Palace of Westminster guards took part in ballot in favour of industrial action

Hundreds of House of Commons security guards have voted for strike action in a move that could cause queues for MPs, staff and visitors, and disruption for parliament.

The Public and Commercial Services Union (PCS), a trade union for civil servants and public sector contractors, said more than 250 guards who provide security at the Palace of Westminster took part in the ballot, with 95% in favour on a 79% turnout.
