John Hemming continues to lift the lid on the big scandals in our lives.
Having revealed the iniquities of a system producing degrees for pastry chefs and failed to make a cheap political point about emigration, he's moved on to public toilets. OK, so 'Toilets, toilets, toilets' isn't much of an election slogan compared to 'Education, education, education,' but it has revealed the existence of the British Toilet Association, a hitherto shadowy organisation. Unusually, John is interested in taking a leak rather than leaking.
Nothing like a safe seat, eh?
