Couples may be allowed to get married naked in naturist weddings under a rethink of marriage law ordered by ministers.

The prospect of brides walking down the aisle of Waitrose rather than one in a church will also be on the cards in a full-scale inquiry into how and where weddings should be staged.

The move to reform wedding law follows David Cameron’s introduction of same-sex marriage.

The 2013 legislation that allowed gay weddings also said the Government would examine changes to the way marriages are solemnised.

As a result, the wedding law review, ordered by ministers to start this week, will look at sweeping reforms which could allow weddings in the open air or in people’s homes and gardens.

It will explore whether weddings may be conducted by non-religious organisations from humanists to political pressure groups.

A paper published yesterday by Justice Secretary Chris Grayling confirmed that among groups that have expressed an interest in changing the wedding laws is British Naturism, the organisation that represent naturists and campaigns to combat prejudice against outdoor nudism.

It said naturists could qualify to conduct weddings if the rules were changed.

And, the paper said, there was concern that liberalising wedding law could bring in commercial competition, with rival private wedding companies vying to attract the custom of brides and grooms, and even supermarkets might be turned into venues for couples to take their vows.
