Polling stations have opened for the European Parliament elections.
Seventy-three members, known as MEPs, will be elected in nine constituencies in England, with seven elected in the West Midlands.
MEPs are elected by proportional representation, in order as listed by their party.
The number of MEPs each party gets is calculated using a formula called d'Hondt, except in Northern Ireland, where the Single Transferable Vote (STV) system is used.
Results will not be announced until all EU nations have voted over the next three days - with the voting process completed by 22:00 on Sunday 26 May.
Polling stations in the UK are open until 22:00.
