Regional news programme ITV News London was off-air this evening and replaced with ITV News Meridan.

The 6pm news bulletin was unable to be shown due to 'power supply problems', the network confirmed. 

Shortly before 6pm, ITV London tweeted: "Due to power supply problems at our London studios, our regional evening bulletin at 6pm will be brought to you by our colleagues at ITV Meridian."

ITV London serves regional news to London and the Home Counties every day. 

News from ITV Meridan, which covers Oxford, Thames Valley and the South East of England, was shown to viewers in London instead.
