THE Welsh Government is "deeply concerned" following reports that passengers on a flight from Zante to Cardiff did not adhere to coronavirus rules.

Public Health Wales has confirmed at least 16 cases of COVID-19 from three different parties who were on TUI flight 6215 to Cardiff on August 25.

Seven of those were infectious at the time of flying and all 193 passengers have been told to self-isolate, it said.

One traveller claimed that the flight was full of "selfish 'covidiots'", with passengers not wearing their masks properly and disregarding the rules.

Education Minister Kirsty Williams told the Welsh Government's weekly press conference that a statement about other flights coming into Wales would be made later on Tuesday.

"The Welsh Government is deeply concerned by the reports from people who were on that flight about the lack of appropriate measures to keep everybody on that flight safe," she said.

"My colleague Vaughan Gething, the health minister, is in discussion with all relevant parties and will be making a statement later today about other flights that may be operating out of Greece and into Cardiff Airport."

On Tuesday, Public Health Wales said one further person with coronavirus had died in Wales, bringing the total number of deaths there to 1,596.

There were a further 51 positive cases of Covid-19 reported, bringing the number of cases to 18,063.

Dr Christopher Williams, incident director for the Covid-19 outbreak response at Public Health Wales, said: "All passengers are being followed up by their local Test Trace Protect teams.

"They should all self-isolate at home, as they may become infectious, even if they have no symptoms. Anyone with symptoms should book a test without delay."

A spokeswoman for TUI said crew are trained to the highest standards and in line with European Union Aviation Safety Agency (EASA) guidelines.

Passengers must wear masks throughout - apart from when consuming food and drink - and are not allowed to move around the cabin.

"A full investigation is now under way as these concerns weren't reported during the flight or before today," the Tui spokeswoman said.
