I am not convinced by David Panter's assurance that postal voting is safe and secret (Letters, April 24).

His explanation does not take into account the question I raised in a letter published the previous day.

I have therefore asked for Mr Panter's further assurance that the ballot papers he receives as the Returning Officer will have been completed by the persons to whom they were sent.

Perhaps, in giving this assurance, he will publish a further explanation of the method employed for ascertaining that the crosses on the ballot papers are actually made by those who sign the declaration of receipt?
