This summer we have sweltered in the hottest temperatures on record.

Being out in the sun for long periods at a time has proved a challenge for even the most dedicated beach-lovers. While men walk around the streets bare-chested, women have stripped down to bikini tops.

Among them was mother-of-two Tracy Wood, who was stunned to be told by staff at Asda to cover up or get out.

Ms Wood was understandably affronted to be called a health and safety risk, simply for attempting to cool off on one of the hottest days of the year.

With temperatures in Sussex rivalling those of the Caribbean and the Mediterranean, why should she have been denied that right? Most of us would not think twice about walking around in swimwear while on holiday and would certainly not expect to be reprimanded by retailers for doing so.

Asda is within its rights to operate a dress policy but, doubtless, temperatures of 100F were not envisaged when it was drawn up.

This year's extraordinary summer perhaps requires a bending of the usual rules.

At the very least, signs should be put up at Asda stores, warning customers what to expect. Challenging customers publicly as they shop only causes unnecessary embarrassment and is a recipe for conflict.
