The 2010 Norwich City Council election took place on 9 September 2010 to elect members of Norwich City Council in England. One third of seats were up for election. The elections took place later in the year than other local elections. Norwich had previously been granted permission to become a unitary authority, with local elections postponed until 2011. When the Coalition Government won the general election earlier that year, Nowich's permission to form a unitary authority was overturned. Because of this, the High Court ruled that those councillors who had stayed on beyond their four-year term were no longer constitutionally elected, and would need to seek re-election. This resulted in there being an election in every ward in September to renew the mandate for the wards.
