I bought a glass-top dining table from John Lewis several years ago and was in shock after it exploded on the hottest day of the year.

I contacted John Lewis but it said I was not entitled to a refund or a replacement. There was a camera and a laptop sitting on the table at the time and the “heat given off by these devices is a known cause of glass breakage in tempered glass”, it told me.
