I’m not sure that voting in polling stations is as secretive as Paul Leake believes (Letters, May 7-13).
Once a poll clerk has identified a voter in the electoral register the presiding officer will write the appropriate registration number on the counterfoil to the ballot paper.
So if the ballot paper was recovered after the count and matched to the counterfoil, the voter’s identity and intention would become clear. Surely, though, this couldn’t happen in the UK?
