A Piccadilly line strike has been suspended less than 24 hours before it was due to begin.
Members of Rail workers union RMT working on the line were planning a 24-hour walk-out beginning at midday tomorrow due to a dispute over pay.
Transport chiefs today said earlier today only a limited service was expected on the line, which would have been the only one affected by the industrial action.
London Underground's chief operating officer Phil Hufton said: "I am pleased that we have been able to reach an agreement with the RMT which means that strike action will be suspended on December 4 adn 5.
"This dispute is over a number of local issues, all of which have been resolved or which we have committed to addressing including honouring outstanding annual leave. This agreement demonstrates what can be achieved when all parties are committed to engaging in constructive discussions."
The RMT said today it agreed to suspend the strike after 'intense negotiations' ensured 'enough progress' was made on the issues.
RMT general secretary Bob Crow had said union members were planning to strike because London Underground had broken the terms of an agreement over conditions made back in May.
