Manchester City and Manchester United fans are facing serious travel disruption for the FA Cup final after train drivers announced fresh strikes in a long-running row over pay.

Aslef rejected a “risible” four per cent pay offer from the 16 train companies it remains in dispute with and announced union members will walk out on May 12 and 31 and then June 3 when Wembley hosts the all-Manchester final.

The Football Association only confirmed on Wednesday that the final will start at the traditional time of 3pm after Metropolitan Police deemed it a high-risk match, therefore insisting upon a kick-off time no later than 4.45pm.

The earlier kick-off allows for fans to travel back from London via public transport, but Aslef’s planned rail strike has thrown thousands of fans’ plans into chaos.

Both clubs are assessing the situation and will be liaising with the FA, authorities and fans groups, with the Manchester United Supporters’ Trust expressing their frustration at the situation.

“A train strike on cup final day will be a huge inconvenience to the tens of thousands of supporters travelling down from Manchester to London on the day,” MUST said in a statement to the PA news agency.

“We need all modes of transport available to cope with the level of demand and the railways are a key part of that.

“We call on the Government and the trade union to get round the table and find a way to avert this industrial action.”

Aslef general secretary Mick Whelan said drivers have not had a pay rise at the companies they are in dispute with since 2019.

“Our executive committee met this morning and rejected a risible proposal we received from the Rail Delivery Group,” he said.

“The proposal – of just four per cent – was clearly not designed to be accepted as inflation is still running north of 10 per cent and our members at these companies have not had an increase for four years.

“The RDG, in turn, rejected our proposals to modernise Britain’s railways and help them run more efficiently, for passengers and for businesses, in the 21st century.

“Consequently, we have today announced three more days of strike action on Friday May 12, Wednesday May 31 and Saturday June 3 at the companies with which we are in dispute, and which are letting down passengers, and taxpayers, so badly.

“We are also withdrawing non-contractual overtime from Monday May 15 to Saturday 20 inclusive, as well as on Saturday May 13 and Thursday June 1.”

The train operating companies involved in the dispute are: Avanti West Coast, Chiltern Railways, CrossCountry, East Midlands Railway, Great Western Railway, Greater Anglia, GTR Great Northern Thameslink, London North Eastern Railway, Northern Trains, Southeastern, Southern/Gatwick Express, South Western Railway, SWR depot drivers, SWR Island Line, TransPennine Express and West Midlands Trains.

The May 12 strike will be held the day before the Eurovision final in Liverpool.

A spokesperson for the RDG said: “This is disappointing news for our customers and staff, more strike action is totally unnecessary and will only heap more pressure on an industry already facing an acute financial crisis.

“Senselessly targeting both the final of Eurovision and the FA Cup final is disappointing for all those planning to attend.”
