Elections could still be cancelled for the Labour-run Exeter City Council where it is possible power would change hands as 13 of the 39 seats are due to be contested.
The leader of Exeter City Council, Phil Bialyk, said he was to discuss the issue with the council’s chief executive ahead of making a decision on whether to request a postponement.
The Liberal Democrat leader of Devon County Council, Julian Brazil, said Plymouth had “done the right thing” and claimed the decision “ramps up” pressure on Bialyk to make a decision.
Brazil said: “In this context, it would be a disgrace if Exeter residents were deprived of the chance to choose who represents them in the Civic Centre.
“If the government is worried about councils being able to deliver services, it should fund us properly and postpone a reorganisation project which is costing millions of pounds and stretching both local authorities and civil servants.”
Devon County Council is holding a special meeting on 9 January to discuss the issue.
