Govia Thameslink Railway (GTR) sought an injunction in the High Court over discrepancies in ASLEF’s ballot of drivers for industrial action. This afternoon, the court ruled in GTR’s favour.

A GTR spokesman said: “We are pleased that the Court has agreed with us and granted an injunction against the ASLEF ballot. This means that any industrial action the union was planning cannot now take place. This will come as a great relief to our passengers.

“Following this ruling, we now urge both RMT and ASLEF to return to the negotiating table."
