All major UK airports now have or will soon have military grade anti-drone equipment, the government says. It comes after the military were called in to help when drone sightings caused delays for around an hour at Heathrow on Tuesday. And drone sightings at Gatwick caused major disruption affecting 140,000 passengers before Christmas. Earlier, the defence secretary said it would "not be right" to ask the RAF to respond to similar incidents in future. Gavin Williamson said all commercial airports needed to invest in anti-drone technology.

Gatwick and Heathrow are to spend millions of pounds on anti-drone technology following the disruption at the Sussex airport before Christmas. The equipment, which can detect and jam communications between a drone and its operator, was deployed by the RAF on a roof at Gatwick last month. About 1,000 flights were cancelled over three days due to drone sightings. Gatwick said it had spent £5m to prevent future attacks, and Heathrow confirmed it would be buying systems. More than 140,000 passengers at Gatwick were affected during 36 hours of chaos between 19 and 21 December.
