Map showing the five electoral wards of the Council of the Isles of Scilly. St Mary's (denoted in grey) elects 12 councillors, whereas four of the other islands elect one each.
No one was nominated for Bryher. Consequently, the Returning Officer was required to order an election to fill the vacancy on a day of their choice before Friday 25 June. It was announced that a notice of election would not be issued until after the May elections had passed.[3]
There was only one nomination for this election, so Andrew Crispin Frazer was declared elected on 28 May 2021.[4]
