London Underground drivers walked out on Friday in a protest over the sacking of one of their colleagues who reportedly drove through three red lights.

Transport for London said the driver in question was offered an alternative role after putting lives at risk by not stopping when indicated to do so.

The 24-hour strike on the District Line, organised by the Aslef union, is the result of a dispute over the treatment of the driver.

Services on the line are expected to be severely disrupted throughout the day.

According to Transport for London, in his first 11 weeks driving, the driver passed through three red lights, two of which are said to have been passed at danger within a four-week period.
