Peter Kavanagh, Unite Regional secretary for London said:
"This eleventh hour intervention still raises more questions than it answers. It beggars belief that Boris Johnson has waited so long to intervene and the mayor has still not been in direct contact with us or responded to our request for a meeting.
"Unite met with the Olympic Delivery Authority last Friday and we believe they were listening, so we cautiously welcome the money being made available by the Authority.
"The mayor cannot now just walk away and leave it to the bus companies. We expect genuine involvement and intervention from the mayor and TfL to ensure the bus companies fulfil their duty to recognise fully the role their workers will be playing in making the Olympics a success.
"We cannot call the strike off until we hear from the bus companies and we are persuaded that TfL is serious about resolving this dispute. With only 36 hours left every minute counts. There are 20 bus operators, it's imperative there's a single forum to meet with the bus companies and TfL's involvement is vital in order to secure a deal."
