No pre-roll ads. The leader of a train drivers’ union says pay negotiations with ministers have stalled over the past four months as fresh rail strikes take place.

Aslef general secretary Mick Whelan said the union had seen “neither hide nor hair” from the Government since the beginning of the year, with “one token meeting” on January 6.
