Plans for a combined authority covering the entirety of East Anglia, including Norfolk and Suffolk, were announced by Chancellor of the ExchequerGeorge Osborne on 16 March 2016 as part of the 2016 United Kingdom budget, with the aim of creating an "Eastern Powerhouse" analogous to the government's Northern Powerhouse concept.[1] Norfolk and Suffolk had initially submitted separate devolution bids, but government ministers called for a joint bid including all three counties.[2][3] Initial proposals had been agreed by all county and district councils in the region, with the exception of Cambridge City Council.
The East Anglia devolution deal was subsequently rejected by Cambridgeshire County Council,[4] with Peterborough City Council also opposing the deal.[5] Plans for devolution in the region were split in June 2016, with one deal for Cambridgeshire and Peterborough and a separate deal covering Norfolk and Suffolk.[6] The Norfolk and Suffolk devolution deal was later scrapped, after several district councils withdrew.[7][8]
The devolution deal was agreed by the constituent local councils in November 2016,[9] and the first meeting of the shadow combined authority was held in December 2016.[10] The draft statutory instrument required for formal establishment of the combined authority was laid in Parliament on 23 January, made on 2 March 2017, and came into force the following day.[11]
