Following the resignation of former councillor Ann Sinnott last week, a by-election to fill the vacancy has been called for 13 September.
Residents of Petersfield ward are being reminded to ensure that they are registered to vote ahead of the poll.
Anyone who is not yet registered to vote must do so by 28 August, by either going online at https://www.gov.uk/register-to-vote or phoning 01223 457048 for a paper application form.
Any residents who have recently received a household enquiry form as part of the annual electoral canvass should note that this is not a registration form.
Householders should respond to the household enquiry form as part of the annual canvass but anyone whose name is not pre-printed on the form will have to make a separate application to register to vote in the by-election.
People who are registered but will be away on 13 September can apply for a postal or proxy vote by downloading a form from www.yourvotematters.co.uk.
The deadline to apply for a postal vote is 5pm on 29 August and for a proxy vote by 5pm on 5 September.
Poll cards will be issued to electors in Petersfield this week.
Antoinette Jackson, Returning Officer for the by-election, said: “This by-election is a chance for Petersfield residents to have a say on how the city council’s services are run. I would encourage people to register to vote, even if they are not yet sure they want to vote.”
