Air France KLM was down by 10.2% in early session trading, Getlink fell 5.7%, while French airports company ADP retreated by 4.8%. Shares in hotels company Accor fell by 4.4%. France said it would bar all people coming from the United Kingdom for 48 hours from Sunday night, including freight carriers, whether by road, air, sea or rail, amid alarm about a rapidly spreading new strain of coronavirus that has caused cases to soar in the UK.
