The biggest London Underground strike in more than a decade is underway, after last-minute talks between Tube bosses and unions ended in acrimony.

Almost 20,000 Tube workers walked out at 6:30pm, crippling tube services until Friday morning and causing severe delays across the capital.

Last minute talks at the conciliation service, Acas, aimed at settling the dispute, broke down late on Tuesday - resulting in the go-ahead of the strike.

Tubes started running down from 5pm, with all 11 lines shut for all of Thursday. Disruption could carry on until Friday morning.

Tubes are expected to be "exceptionally busy" between 4pm and 6pm on Wednesday - just after the Budget - as people try to get home before the 24-hour strike officially starts at 6.30pm.
