Rail and Tube strikes planned for next week are to go ahead as talks to avert the industrial action have failed, union leaders said on Saturday.
The Rail, Maritime and Transport union (RMT) said it had held discussions in the past few weeks at senior levels with Network Rail, train operators and London Underground to resolve the dispute over pay, jobs and conditions.
General secretary Mick Lynch said: "Despite the best efforts of our negotiators no viable settlements to the disputes have been created."
