How does voting on a small island work?

It is very similar to any where else in the country. We have a full polling station set up at the Island Hall with everything that's needed - a doorbell in case help is required accessing the building, a magnifying glass in case you need help to see the ballot paper, freshly sharpened little pencils and of course a big black ballot box for slightly less than a maximum 100 votes. What might be different is that we only need one voting booth and our friends, Anna and Robin from St Martin's Water Sports, are the presiding officer and the poll clerk; making the rules on photo ID mildly farcical but quite rightly adhered to. Just like on the mainland the polling station is open from 7am to 10pm. I asked Anna, 'If every single person on the electoral role had voted could you close early?' Anna replied, 'It's never happened but I would be tempted to call the returning officer for Scilly at that point and ask permission.' Obviously Anna and Robin aren't rushed off their feet, although a summer vote did mean they had plenty of curious holidaymakers dropping in to ask questions. According to Robin one of the most important things to get them through the long day is a well stocked snack buffet! Weather permitting at 10.30pm the ballot box is collected and taken by boat to St Mary's to be opened and the votes counted. The results are then sent through and added to the St Ives constituency count.
