More than 500 people have registered to vote in Brighton and Hove in the past month.
And tomorrow (Thursday 5 May) they will be among 203,838 people eligible to vote in the elections for Brighton and Hove City Council and the referendum on the parliamentary voting system.
The number people who have asked for a postal vote has risen to 31,873 – up from 27,709 six months ago.
Postal votes need to reach the returning officer by 10pm tomorrow.
And the council said that there were currently 1,605 first-time voters on the electoral roll.
A council spokesman said that polling stations would be open from 7am to 10pm tomorrow.
He warned that no ballot papers would be given out after 10pm.
The warning follows angry scenes in queues and polling stations in some parts of the country at the general election when large numbers arrived to vote late.
He said: “Staff will not be able to give you ballot papers after 10pm so do arrive in good time.”
He added that, while it would be useful for voters to take their polling card with them when they vote, they don’t have to.
The nationwide referendum on the voting system used for parliamentary elections will ask: “At present, the UK uses the ’first past the post’ system to elect MPs to the House of Commons. Should the ‘alternative vote’ system be used instead?”
Most people will be able to vote in both the local elections and the referendum.
Any British, Commonwealth or Irish citizen aged over 18 and who is registered to vote can take part in the referendum.
The local elections are open to the same people as well as citizens of other European Union (EU) countries.
