LONDON (Reuters) - London is set for a day of huge transport disruption on Thursday after train drivers' union ASLEF said it would go ahead with a planned 24-hour strike on the London Underground rail network.

The strike, the second in less than a month over plans to introduce a new night service from September, will start from 9:30 pm on Wednesday.
