HUNDREDS of Palace of Westminster security staff will stage a New Year’s Eve strike on Wednesday — threatening Speaker Sir Lindsay Hoyle’s bash.

More than 300 Public and Commercial Services (PCS) members are walking out in a dispute over pay and terms and conditions.

Their boss, the Speaker of the House of Commons, may cancel his key charity event to be held this evening, unless he forks out for extra security cover.

The security staff’s fourth day of strike action this year is over the employer’s removal of six days’ annual leave from members’ contracts, pay stagnation, worsening conditions and a widening ethnicity pay gap.

PCS general secretary Fran Heathcote said: “The employer has reduced members’ annual leave and incorrectly claimed that staff had agreed to it.

“This recent cash offer put to workers is nothing short of an insult.

“Our members want to negotiate but the Speaker won’t talk.

“Any MPs disappointed not to attend Sir Lindsay Hoyle’s charity event might think about donating to the branch’s strike fund instead.”
