Leader of Cumbria CC, Rex Toft, the MP for Copeland Jack Cunningham, MP for Workington Tony Cunningham, and leaders of Copeland and Allerdale BCs, had a meeting with small businesses minister Nigel Griffiths.
Mr Toft had earlier echoed the widespread welcome for the government's decision to base the headquarters of the Nuclear Decommissioning Agency in West Cumbria.
Mr Griffiths was urged by the MPs and councillors that the NDA should be given the duty, rather than merely the power, to invest in the socio-economic structure of the area.
It was also impressed that the Government needed to respond to the general level of unemployment in West Cumbria and that major investment would be needed to strengthen its economy.
Mr Griffiiths had earlier made a keynote speech at the first day of a two-day conference at Westlakes Research Institute entitled 'nuclear clean-up: skills, education and environmental challenges'.
