Dame Vera announced in May she was stepping down to become the new Victims’ Commissioner, taking over from Baroness Newlove in June 2019.
She was elected as the area's first PCC in 2012, and in that time has taken an active role in promoting the views of victims, also serving as the Association of Police and Crime Commissioner’s lead for supporting victims and reducing harm.
Rules mean an election must take place to fill the vacancy within 35 days, and the date has been set for July 18. Polling stations will be open between 7am and 10pm.
It is the second time voters in Northumberland have gone to the polls this year, after the European Parliament election on May 23.
The Northumbria Police Area covers the local authority areas of Gateshead, Newcastle, Northumberland, North Tyneside, South Tyneside and Sunderland.
This will be the third time that voters in the area have gone to the polls for a commissioner. The first commissioner election was held in November 2012 after the posts were introduced, and the second in May 2016.
In 2016, there were more than one million (1,035,492) registered electors in the Northumbria Police Area, including more than 300,000 (323,155) postal voters.
The Northumbria result will be announced from the area returning centre in Sunderland on Friday July 19, where Patrick Melia, the chief executive of Sunderland City Council will be returning officer.
Anyone who has not yet registered to vote in the election should do so by Tuesday 2 July.
