First Minister Carwyn Jones called for a "legislative window" in Westminster to implement the recommendations of the Silk Commission before the next general election during the weekly session of AMs' questions on 20 November 2012.
The Silk Commission was set up by the UK government to look at the future of devolution in Wales.
Part one of the commission's findings were published on 19 November 2012, recommending that the Welsh assembly should be given tax varying powers by 2020.
In response to questioning by the Leader of the Welsh Conservatives Andrew RT Davies, the first minister said: "We support part one of Silk, we are happy to see it being taken forward, and look forward to his party taking Silk forward in full before the end of this term."
Leader of the Liberal Democrats, Kirsty Williams said that all four parties in the assembly had worked together to ensure that the commission was set up in the first place.
She sought assurances that the first minister had disscussed Silk with his party centrally as well as with the UK government, to ensure cross-party support in Westminster for its implementation.
The first minister said that it was his priority to ensure that Silk was implemented "in full" including changing the funding formula for Wales.
He welcomed Mrs Williams' support to changing the Barnett Formula.
"I have been in discussion with Labour ministers... and I have already raised the issue with the secretary of state," he said.
Mr Jones also answered questions on child poverty, rolling stock and the performance of the ambulance service in south west Wales.
