Under current pricing a single fare from TfL zone four to zone one costs the commuter £4.40 however from next year this could rise to £4.60.

In a letter to the Mayor, Ms Haigh wrote: HMG [His Majesty’s Government] expects you to consider the full range of revenue raising powers at your disposal as part of TfL’s business planning and to confirm to HMG your plans to ensure TfL continues to improve its financial sustainability in the medium term.

‘You should note that HMG’s assessment of TfL funding needs in Phase 2 of the Spending Review will be conducted against a baseline scenario where TfL rail fares rise in line with national rail fares this year.’

For the next twelve days, commuters who regularly use London’s  tube network will have to plan their journey ahead of time as strikes are set to heavily impact the capital’s transport systems.

Workers will walk out between November 1 and November 12 in a dispute over pay despite TfL bosses putting forward what they say is a ‘fair’ deal that will see wages rise an average of 4.6 per cent.

Trade union Aslef – representing thousands of Tube drivers, who are paid at least £63,000 a year – has ordered 24-hour walkouts on November 7 and November 12.

The RMT union has also said swathes of maintenance and emergency staff will go on strike between November 1 and November 8 amidst a ‘wholly inadequate’ pay offer.

Planned strikes will likely shut down the entire Tube network for at least two days – with other action likely to limit the number of services that can run and could lead to stations being closed at short notice.

Crunch talks are understood to be continuing between shop stewards and TfL management in a bid to see off the strikes.

Tube drivers are to go on strike in Novemeber, Aslef has said, after discussions around pay broke down. The RMT union says its members will also strike

Aslef had called off strikes in April following talks over driver welfare, training and working conditions – but the union says it is unhappy with the pay deal on offer.

It claims TfL is unwilling to equalise working conditions with drivers on the Overground or Elizabeth Line, which are run by external companies.

Finn Brennan, Aslef organiser on the London Underground (LU), said: ‘We don’t want to go on strike. We don’t want to make travelling in and around the capital more difficult for passengers and we don’t want to lose a day’s pay.

‘But we have been forced into this position because LU management won’t sit down properly and negotiate with us.’

Industrial action extends in part to other Aslef-affiliated members of Underground staff within TfL.

Management staff will strike on November 7 and November 12, and an overtime ban will be in place from November 3 until November 16.

Engineering drivers will also walk out for 24 hours from the evening of Friday November 1 for 24 hours into Saturday November 2, with an overtime ban in place between November 1 and November 8.

The average Tube driver salary as of November last year was £63,901, according to a freedom of information response issued by TfL, though thousands are paid in excess of £70,000.

TfL said on average the pay rise offer for TfL workers was 4.6 per cent – but Mr Brennan said the offer for Tube drivers was lower at 3.8 per cent, and did not include paid meal breaks enjoyed by drivers on the Elizabeth Line and Overground.

It is understood that TfL also offered a £450 one-off payment that would give the drivers a total 4.5 per cent pay rise.

The union rep added: ‘ASLEF members have been extremely patient as talks have dragged on – with no real progress – for months on end.

‘Sadly, it is clear, once again, that Underground management will only get serious about reaching a settlement if there is the prospect of strike action.’

The RMT, meanwhile, says its own members are striking because the pay offer ‘falls short’ of what it says members deserve and would create divisions between staff.

Workers including maintenance staff, track controllers and control room members will strike on various dates between November 1 and November 8.

General secretary Mick Lynch said: ‘No trade union can accept any pay proposal where management decide which of our members gets a pay rise and those who do not.

‘We have repeatedly urged London Underground to offer a deal that ensures all staff are covered by collective bargaining, yet management remains fixated on imposing pay structures without our agreement.

‘Our members have been left with no choice but to take strike action to defend their terms and conditions.

‘We remain open to negotiations, but London Underground must come back to the table with a comprehensive, consolidated offer that respects the rights of all our members. Until then, our industrial action will continue as planned.’
