The Government faces protests by rail workers and passengers over the crisis at Southern Railway as another train company is threatened with strikes.
The Rail, Maritime and Transport union (RMT) will demonstrate outside the Department for Transport (DfT) today amid claims that it has put a "blockade" on talks to end the bitter dispute which has led to strikes this week.
The union said it was "within an inch" of reaching an agreement last week and repeated its claim that the Government had "sabotaged" any deal, again naming Transport Department official Peter Wilkinson as "directing operations from outside".
The Campaign for Better Transport and a Southern passenger group, the Association of British Commuters, plan to march to the DfT later today to call on the Government to take urgent action to help resolve the row over plans to change the role of conductors.
Industrial relations on the railways worsened after RMT members on Virgin East Coast voted to strike in a separate dispute over jobs, working conditions and safety, backing walkouts by 84%, with nine out of 10 supporting other forms of industrial action.
