London Underground says an extended strike by power workers is not affecting Tube services. Staff have walked out until July 15 in a dispute over pay, pensions and working conditions.
Richard Jones, London Underground's head of command and control, said:
"Whether this action lasts for eight days or longer, our customers will not be affected. We simply will not give in to wild pay claims at the expense of fare and taxpayers.
"The unions have already rejected lump sum payments of £13,700 and salary increases of up to 7% in exchange for increased productivity."
