Transport Secretary Grant Shapps has warned the country’s biggest rail union that this week’s strikes will be a “huge act of self-harm” which could jeopardise the future of the industry.

Mr Shapps dismissed a call from the Rail, Maritime and Transport (RMT) union for the Government to intervene as a “stunt”, saying the union had been “gunning” for industrial action for weeks.

However, Labour said ministers needed to step in to prevent the network “grinding to a halt” in a dispute over pay, conditions and job losses.

On Saturday, the RMT confirmed that strikes at Network Rail and 13 train operators will go ahead on Tuesday, Thursday and next Saturday, and on London Underground on Tuesday.

General secretary Mick Lynch said the union had no choice but to act after the train operators had still not made a pay offer when talks adjourned on Thursday.

“We have to fight this because we haven’t had any pay rises, we are faced with thousands of job cuts and they want to rip up our terms and conditions in a form of hire and re-hire that is internal to the railway,” he told Sky News’s Sophy Ridge on Sunday programme.

He warned that industrial action would continue if there was no settlement with other rail unions balloting their members on strike action.

“If there is not a settlement we will continue our campaign. I think there are going to be many more unions balloting across the country because people can’t take it any more,” he said.

Mr Shapps, however, said the union had been “gunning” for industrial action for weeks and accused it of “punishing” millions of “innocent people” who will be affected by the strikes.

“Of course, it is a reality that if we can’t get these railways modernised, if we can’t get the kind of efficiency that will mean that they can work on behalf of the travelling public, then of course it is jeopardising the future of the railway itself,” he told the Sophy Ridge on Sunday programme.

“I think it is a huge act of self-harm to go on strike at the moment. I don’t believe the workers are anywhere near as militant as their unions who are leading them up the garden path. They are gunning for this strike. It is completely unnecessary.

“There is a sensible pay deal, there is a sensible modernisation of the railway which would enable much more flexibility, but the unions need to understand the world has changed and people don’t necessarily need to travel in the way they did in the past.”

For Labour, shadow communities secretary Lisa Nandy said that only the Government could now resolve the dispute and prevent the strikes going ahead.

“We know what it means when the railways grind to a halt, but that’s why the Government has got to get round the table with the cleaners and the ticket office staff and the station workers to resolve this because they’re the only people who can,” she told the programme.

“During the pandemic they took the right to negotiate back from train operating companies, so they’re the only people who can resolve this and yet they’re not prepared to.

“The biggest problem that this country has is not militant workers, it’s a militant Government.”

In a speech to the Labour Local Government Association conference in Warwick, Sir Keir Starmer said ministers wanted to see the country “grind to a halt” so they could “feed off the division”.

“Instead of grown-up conversations to take the heat out of the situation, they are pouring petrol on the fire,” the Labour leader said.

“Instead of bringing people together in the national interest, they are stoking division in their political interest.”

Mr Shapps dismissed the claim, telling the BBC’s Sunday Morning programme that many people would find the comments “pretty offensive”.

However, the calls for the Government to intervene were joined by former minister Jake Berry, the leader of the Northern Research Group of Tory MPs, who said ministers needed to avoid widespread disruption.

“By training I’m a lawyer and I can tell you that the only way out of a dispute is via negotiation,” he told Times Radio.

“I call on all parties, including the Government, to get around the table because it’s going to have a huge negative impact on people’s lives.”
