A LABOUR MP left workers aghast yesterday after he appeared to agree with a call to sack striking Tube staff.

Birmingham MP Khalid Mahmood “liked” the Facebook status of a right-wing Labour activist which read: “Automate the Tubes. Sack all the striking TfL staff. Retrain the others. That is all.”

The comment came a few hours before staff across London’s Underground network were due to walk out for 24 hours in a dispute over new working patterns when the Tube starts running through the night in the autumn.

Labour leadership contender Jeremy Corbyn yesterday tabled a Commons motion condemning the “disgraceful” treatment of Tube workers and calling on London Mayor Boris Johnson to withdraw compulsory night working.

The motion warned that night work can have a serious effect on workers’ health and compromise employees’ family and social life.

It deplored the fact that Tube workers “who have only just recently been rightly lauded as some of the heroes of 7/7 are now being treated in such a disgraceful manner.”

Members of unions RMT, TSSA and Aslef downed tools last night alongside general union Unite, which also represents Tube staff.

Aslef Tube organiser Finn Brennan said talks had broken down on Tuesday afternoon after bosses “didn’t indicate they would give ground on anything at all.”

He said that Tube managers had told workers their pay offer would be withdrawn unless it was accepted by 6.30pm on Monday — and then told journalists the following day that the offer was still on the table.

“London Underground’s tactics didn’t help to build trust,” he said.

The London mayor branded the strike “mad” and its leaders “narrow-minded union barons.”

Mr Johnson said “pig-headed” workers’ demands would not be met even if they went on strike “until they are blue in the face.”

But workers were more surprised to hear of anti-strike sentiment from a Labour MP.

Mr Mahmood did not respond to answerphone messages and emails requesting comment yesterday afternoon.

Mr Brennan said: “I’m sure that’s something he’ll have to explain to his local Labour Party and the people who voted Labour in his constituency.”
