Commuters using the Central Line could face "severe disruption" on the London Underground (LU) tomorrow ahead of threatened strike action by train drivers.

Transport for London (TfL) said Central Line services on the Tube will be "severely affected" should the action go ahead, which was backed by members

Members of Aslef on London Underground's Central Line will walk out for 24 hours at midnight, in a strike which will also hit the Waterloo & City Line.

Parts or all of both lines could be suspended and if trains do run, they will be at a reduced frequency. Central Line trains are not expected to run through central London.

TfL is advising passengers to check before they travel.

The two lines are used by up to two million passengers a day. Other services are expected to operate normally.

Nigel Holness, LU's operations director, said: "We will have staff and volunteers across the network to help customers with their journeys but I advise people to plan ahead and check before they travel."

Finn Brennan of Aslef said: "This dispute has been brought about by management intransigence on a range of issues, but at its heart is management's refusal to treat drivers with the respect and dignity they deserve at work.
