Elsewhere in Europe, worried ministers in France, Cyprus, and Austria have tightened travel restrictions, while Paris has also cancelled its New Year's Eve fireworks.

Denmark has closed theatres, concert halls, amusement parks and museums over the Christmas period, and Germany's regional health ministers have urged the national government on Saturday to introduce tougher rules on people arriving from the UK.
