The Commission for Integrated Transport (CfIT), which monitors and advises the Government on transport policies, will continue its advisory role but will no longer monitor policy progress.
The Department for Transport said: 'This recommendation was a result of three factors. A number of other organisations already have an overlapping role monitoring the achievement of the plan.
'Secondly, it generates unavoidable tensions with the department, which can only undermine CfIT's potential role as policy adviser. Thirdly, when some members are asked to be critical of their own organisation it inevitably generates tensions within the commission's board.'
