Strikes on London Underground services will take place this Wednesday (July 8) until Thursday (July 9).

The strikes, described as "the most chaotic in a decade", come following a dispute over the introduction of an All-Night Tube service, due to begin in September.

If you travel regularly on the Tube in and around London, or are looking to travel to this year's Wimbledon Tennis Championships by Tube, here's all the information you need about the upcoming strikes:

When are the strikes?

RMT Unite and TSSA members are planning 24-hour strike action on the Tube from 6.30pm on Wednesday (July 8).

ASLEF drivers are also planning 24-hour strike action on the Tube from 9.30pm on Wednesday. There will officially be no Tube service from late afternoon on Wednesday until Thursday (July 9) evening.

Southern rail engineers are to stage a five-day strike, walking out from 5pm on Sunday (July 12).

DLR, London Overground and Transport for London (TfL) rail staff are not on strike.

Which services are affected?

The entire London Underground service, excluding the DLR and London Overground lines, will be shut down; a total of 11 lines and 260 stations closed.

Further, First Great Western services to and from Paddington also face disruption from Wednesday evening to Friday, due to a 48-hour strike by RMT members in a separate row over working conditions.

The strikes are expected to be the most chaotic for a decade.

Why are people striking?

London underground workers are striking in a row over pay and the introduction of the All-Night Tube service, due to begin in September.

A ballot by the ASLEF union saw 98% of votes in favour of a walkout, on a turnout of 81%.

When the strikes were first announced, Steve Griffiths, London Underground's chief operating officer, said: "We have been in discussions with the unions since February, and are still in the midst of negotiations.

"We recognise the hard and valuable work of our staff and want to give them a pay rise this year and next. We also want to minimise the impact of the Night Tube on our people, and compensate those it will affect most. But pay levels for our staff are already fair, and any increase must be sustainable.

"Londoners and businesses overwhelmingly back the Night Tube, and trying to block something that will transform our city, and create more jobs, is short sighted."

A spokesman for TfL said: "If the strike goes ahead, there will be no Tube service from late afternoon on Wednesday and no Tube service at all on Thursday (July 9).

"All other public transport services and roads will be much busier than usual, so please check before you travel."

If you are catching any overground trains, be prepared to stand up or wait for longer periods of time.
