An agreement between London Underground and the ASLEF and RMT rail unions could have averted the threat of further tube strikes.
The unions have suspended the strikes after they last week struck and agreement with London Underground to establish a commission to monitor safety standards.
The committee will consist of 50 per cent trade union representatives and 50 per cent London Underground Limited representatives.
Talks continue to guarantee lifetime jobs for existing tube staff after its partial privatisation.
ASLEF and RMT have vowed to continue strike action if the talks fail – even though a High Court ruling will require members taking part in future disputes to reveal their pay grades and job locations.
