The UK's airports and trains experienced delays, with the London Stock Exchange and the National Health Service among the other organisations in the country dealing with the fallout of a global IT outage on Friday that has grounded planes and caused chaos around the world.

The outage, believed to be related to an issue at US-headquartered prolific cybersecurity firm Crowdstrike and Microsoft, seems to be affecting Windows PCs globally and has also forced 'Sky News' off the air.
