Tube workers are poised to take strike action that could bring London Underground services to a halt next month.
Commuters and tourists could find services severely disrupted
Members of the RMT transport union voted overwhelmingly in favour of a walkout on the underground from 6.59pm on Tuesday June 9 until 6.58pm on Thursday June 11.
The union is in dispute with LU and with Transport for London over pay, working conditions and the fate of some 3,000 at-risk jobs.
The union said that Tube bosses were threatening to tear up an agreement aimed at safeguarding jobs and had refused to rule out compulsory redundancies.
The RMT maintains that LU has also refused to budge from an "unacceptable" five-year pay offer.

Union called vote result 'magnificent'
The union claims the deal gives no real-terms increase for four years, and could even entail a pay cut.
The union says that TfL is also threatening compulsory redundancies as part of a £2.4bn cuts package.
RMT general secretary Bob Crow said today: "This is a magnificent result which underlines the anger that has been provoked by management in their confrontational approach on pay and job security.
"If LU and TfL want to avoid confrontation they should withdraw their plans to slash jobs and guarantee there will be no forced redundancies, start talking seriously about pay and call off the bully managers."
