How to cycle safely during the Tube strike
07:30 , Tom PlaceMore commuters than usual are expected to cycle to work this week, as they explore alternative methods of travel due to the strikes.
The morning commute can be a daunting prospect for the novice cyclist - sharing the road with buses, lorries and cars also means running the risk of injury.
The Standard has published a guide to help you cycle safely during the Tube strikes - you can read the full article here.
London's roads clear

How to beat the strikes
07:17 , Tom PlaceWhile all London Underground lines will be affected by the Tube strikes, there are still plenty of ways to get around the city if you plan ahead, and several services will continue to run as normal.
The Standard has pulled together a guide detailing how to avoid the worst of the chaos amid the strikes this week.
Why are the Tube strikes happening?
07:10 , Tom PlaceToday’s planned walkout will be the first in a series of six 24-hour strikes by drivers on the Tube in the coming months.
It comes after Transport for London (TfL) offered Tube drivers the chance to work a four-day week - but the RMT rejected the offer, citing driver fatigue and compromising safety, as the changes would mean drivers worked longer shifts on days they worked.

Tube strikes to begin at midday
07:02 , Tom PlaceThe London Underground strikes will begin at midday today for 24 hours, and again from midday on Thursday (April 23) for 24 hours.
Union chiefs have been accused of timing the two 24-hour walkouts so they impact on the capital’s transport network over four days rather than just two.
Zack Polanski’s Green Party have been slammed over their support for the RMT union’s strikes.
Shadow Transport Secretary Richard Holden told the Standard: “We can see the chaos the Greens would bring to Britain.
“Strikes, disruption, and making ordinary working people pay the price for their weird far-left ideological politics.”
Mildmay line part suspended
06:56 , Tom PlaceThe Mildmay line is currently partially suspended between Willesden Junction and Richmond, as a fire near the track in the South Acton Area means the line is blocked.
Trains that would run between the two stations will terminate and start back at Willesden Junction.
There is a good service on the rest of the line.
Windrush line part suspended
06:52 , Tom PlaceThere is currently no service on the Windrush line between Sydenham and West Croydon due to a signal failure at Brockley.
There is a good service on the rest of the line.
The signal failure is also affecting a number of Southern and Thameslink services, including towards London Gatwick Airport.
Trains have to run at reduced speed on some southbound lines, with this disruption expected for most of the day.
