On Wednesday the Association of District Councils' general purposes committee decided the Local Government Association should go ahead even if some councils do not join.
The committee is to propose to a special meeting of the association on 24 April a motion that 'instructs the executive committee to take such necessary steps to bring about the dissolution of the ADC and any other consequential action needed'.
Last week county group leaders said they were opposed to establishing the Local Government Association next year, after environment secretary John Gummer announced an extension of the local government review. Instead they want a federal structure to start in 1997.
Association of Metropolitan Authorities chairman Sir Jeremy Beecham has reaffirmed his support for a single association, raising the prospect of counties being isolated from the rest of local government.
