It's early in the morning on the 7th May 2015. A man holding a clipboard stands outside the Westhill Hall in central Brighton, UK. He is volunteering for the Green party as an unofficial teller. Westhill Hall has been commandeered along with hundreds of other community buildings across the country to be used as a polling station. A lady wearing a raincoat and hat leaves the polling station where she could have cast her vote for the UK's general election and city council elections.
