Dutch authorities are to write Britain another multimillion-pound cheque in a fresh bailout of the UK railways.

The Netherlands finance ministry has confirmed that additional parent company support will be required in 2019 to fund spiralling losses on the sprawling Greater Anglia rail franchise.

Meanwhile, the spectre of Dutch domestic rail prices being hiked to prop up the finances of Britain’s train franchises has been raised by politicians.

Labour’s shadow transport secretary Andy McDonald labelled the situation a “huge concern” and accused Chris Grayling of “gross negligence”.

Last month, The Daily Telegraph revealed state-owned train operator Nederlandse Spoorwegen (NS) led an £80m rescue package of the UK network, which operates more than 1,300 train services every day.

Greater Anglia is in dispute with the Department for Transport over what it has called a “flawed mechanism”, contained in a complicated clause within the franchise agreement that could cost hundreds of millions of pounds.

A similar clause is one of a number of problems facing the beleaguered South Western Railway. Owner FirstGroup recently admitted it is also in talks with the DfT over the clause, which links payments to the DfT to London employment figures.
