With an upcoming parliamentary by-election, Sharon discovers that Tracey did not register her to vote in Chigwell. However she did register Darryl, not wanting to admit he was in prison. Darryl agrees that Sharon can buy his vote for £350. Meanwhile, Dorien is backing the Green Party as she fancies the party's agent. While Sharon avidly votes Labour, Tracey is unsure whom to vote for, so she arranges for each candidate to pay her a visit. At the polling station, Tracey votes Labour, as does Dorien when she finds out the agent is having a relationship with the Green candidate.
