Postal Fraud post mortem

As with the millenium bug, fears of widespread electoral fraud through the postal ballot system apparently seems to have been unfounded. I am not aware of any spurious election results or widespread "nobbling" of the election in marginal seats. Some votes do seem to have disappeared whilst other's, notably John Humphries of BBC Radio 4, was impersonated and there was the usual collection of anomalies, eighteen month old toddlers receiving ballot papers and occasional EU nationals. As this does not appear to be widespread and anomalies always occur, should postal voting continue unreformed? The case for reform no longer seems as strong without any evidence to the contrary!!
