Sainsbury's and Tesco have joined other UK supermarket chains in removing disposable barbecues from their shelves during the heatwave.

Marks and Spencer, Aldi and Waitrose have already halted sales and fire brigades have called for all retailers to follow suit as the risk of sparking fires rises during the heatwave.

According to the BBC, Sainsbury's said the policy was a precautionary measure, but did not say how long it would continue. Tesco said the move was temporary.

Once weather conditions allow, disposable barbecues will be made available again, Tesco said. It also said small metal portable barbecues remained on sale as an alternative.

With the UK in the middle of its second heatwave this summer, fire services are warning of "tinderbox conditions" and have asked people not to use barbecues in high risk places, such as balconies and on dry grass, after a steep increase in the number of call-outs.

Last week Marks and Spencer responded saying it wanted to "help protect open spaces and reduce the risk of fires" by removing the single use portable barbecues from sale.

Aldi and Waitrose had already stopped sales back in March, due to the burden on the environment more generally, including the impact of the single use plastic, metal and card.

Morrisons, and the Co-op say they do not sell disposable barbecues close to UK national parks.
