The British Toilet Association is demanding a minimum level of provision set by government, claiming that British public loos were once the 'envy of the world' but now fall short.
BTA director Richard Chisnell warns political parties that voters are 'feeling increasingly isolated when it comes to satisfying their daily toileting needs away from home'.
He blames the decline in standards on the Government's policy of allowing 'market forces' to dictate the level of investment in public bogs.
The campaign insists a statutory obligation for all public service providers, from education, health and local authorities to transport operators, would be a sure-fire vote winner - and not just among older voters.
Those politicians scoffing at the issue should beware, says Chisnell, who claims a recent Tory victory in the Shepway District Council elections can be directly attributed to toilet policy.
