A fresh Tube strike appears more likely to take place this week after a union rejected the latest offer from transport bosses.

Unite - which represents Tube engineers and power staff - said the latest proposal did not go far enough, especially on working patterns for the new all-night Tube services.

The union is one of four which were planning to walk out for 24 hours from on Wednesday evening in their ongoing dispute over the Night Tube.

The other three unions, The Rail, Maritime and Transport union, Aslef and the Transport Salaried Staffs Association, are set to decide whether to accept the latest offer from London Underground today.

Union bosses are unhappy at the pay and conditions over the new Night Tube, set to begin on September 12.

LU made a revised offer last week which will be discussed by union leaders before the two sides resume talks at the conciliation service Acas.

The new offer has not been increased in value but LU said it had been "reshaped" in response to concerns about the work-life balance of staff who will work on the new service.

The Tube network ground to a half four weeks ago when all four unions mounted a strike over the Night Tube plans.
