Rail unions have admitted that they are co-ordinating a wave of summer strikes which will disrupt the journeys of millions of people in a bid to "maximise the impact" of their industrial action.

Eurostar passengers face the prospect of Bank Holiday chaos after workers from the RMT and TSSA announced that they will hold two strikes this month, including over the Bank Holiday.

RMT announced that it will take industrial action, which is over ensuring that train managers can enjoy a "good work-life balance", after a ballot of just 55 workers.

The three main railway unions are expected to hold at least five strikes in coming weeks that could cripple large stretches of the railway network.
