Transport bosses have stumped up another £5m to try to settle the row over Olympic bonus payments for bus drivers before tomorrow's strike.
The additional money, from the private bus operators, would guarantee £583 for every bus worker in London.
If the payments are restricted to drivers only on routes directly affected by the games, the amount rises to more than £700. Transport for London has also offered to share the profits from extra fares generated by the Olympics.
The surplus wold be split 50/50 between bus staff and TfL. Officials from the Unite union and the bus companies are at the concilliation service ACAS for a third day of negotiations.
