Polling stations across Lincolnshire have opened for the county's first directly elected mayor.
All 70 seats across Lincolnshire County Council are also being contested.
Registered voters will be able to cast their ballots from 07:00 to 22:00 BST on Thursday.
The result for the mayoral election is expected to be announced at Grimsby Town Hall on Friday.
As head of the Greater Lincolnshire Combined County Authority (GLCCA), the mayor will represent around 1.1 million people who live in the combined county.
They will oversee decisions on housing, public transport, infrastructure, economic development, business, skills and regeneration.
A devolution deal approved by the government last September resulted in the creation of a Greater Lincolnshire Combined County Authority (GLCCA).
This has brought together Lincolnshire County Council, North East Lincolnshire Council and North Lincolnshire Council.
