HUNDREDS of Parliament security staff walked out on Budget day in a row over terms and conditions.

Public and Commercial Services union (PCS) members launched a 24-hour strike at 7am, mounting picket lines outside Parliament.

PCS general secretary Fran Heathcote said: “No-one deserves to have their contracts effectively torn up and rewritten.

“These members have been treated disgracefully, despite working day and night to ensure the safety of MPs, Lords, staff and visitors in the UK’s national Parliament building.

“PCS demands that the employer comes to the table to talk, to listen to our members’ serious concerns, and to guarantee a fair settlement.”

The guards previously took action in September.

A Parliament spokesperson said: “The decision to take further strike action is disappointing, particularly given the continued engagement undertaken to try to resolve outstanding concerns.

“We remain committed to working closely with staff and unions to address the issues raised and to reach a resolution.”
