The Rev Peter Mullen, chaplain to the London Stock Exchange, called for homosexuals to be tattooed with warnings about the perils of gay sex in a cigarette-packet-style health warning.

In his blog, Mr Mullen wrote: 'Let us make it obligatory for homosexuals to have their backsides tattooed with the slogan SODOMY CAN SERIOUSLY DAMAGE YOUR HEALTH.

'In addition, the obscene 'gay pride' parades and carnivals should be banned for they give rise to passive corruption, comparable to passive smoking. Young people forced to witness these excrescences are corrupted by them.'
