An LBC caller has said Britain is 'breeding a nation of melts' after the heatwave shut more than 1,000 schools and workplaces across the country.Caller James said tradesmen soldiering on with outdoor work this week were the 'backbone' of Britain, while the decision to close schools was leaving children 'ill-prepared for real life in this hard world'.It comes as a 'heat dome' across Europe has prompted a rare red warning for extreme heat in London, the south, parts of the Midlands and southeast Wales, with record-breaking June temperatures of 40C forecast.But James didn't mince his words as he described those out working in yesterday's heat as nothing short of heroic.He told presenter Henry Riley: 'There were six men and they weren't all young 20-somethings, some of them were probably as old as 45, stripped down to their shirts, just shorts and boots and their belts.'And they were handballing all this heavy-duty steel scaffolding. It was 33C in the temperature on my car.'It's men like that that are the backbone of every country on this planet.'He went on to hit out at 'melts' who 'go on about children and duty of care'.'We are breeding a nation of melts. We've got children that as you've already said are locked in their bedrooms. They are so ill-prepared for what real life in this hard world is like.'Presenter Mr Riley praised his comments, but added: 'There is a line though, isn't there. You've got to be sensible with it.' Caller James was speaking to presenter Henry Riley this morning and praised tradesmen soldiering on with outdoor work this week as the 'backbone' of Britain
