All Tube lines open on second day of strike
London Underground claims support for strike action is weakening as more services run.
London Underground claims support for strike action is weakening as more services run.
Boris Johnson has labelled planned strike action on the Tube as "pointless" after talks aimed at averting the walkout failed.
Mr Johnson said commuters and businesses would suffer as a result of the actions of a "few narrow-minded union barons".
"I urge the RMT to call off this pointless strike and get back round the table with London Underground and the three other unions who've chosen not to strike," the mayor said.
"It seems the RMT leadership is set against modernisation and has no fresh ideas of its own.More than 600 people have asked for voluntary redundancy and yet, without consulting any of their own members, the RMT is suddenly insisting that London Underground halt this process.
"Commuters and businesses will suffer because a few narrow-minded union barons are currently flexing their muscles in a fight for the leadership of a union where just 30% of members support a strike."
The fight broke out as the train approached Aldgate East station on Monday night, hours after the Tube strike began.
Fog and train delays added to the misery depriving many travellers of alternative ways to get to work.
