Londoners who crowded on to trains to leave the capital on Saturday night were “totally irresponsible”, the health secretary has said.
London has moved into tier-four restrictions, meaning it is illegal to leave the capital from 00.01 GMT Sunday unless for essential travel.
Footage shared on social media showed large crowds at St Pancras station.
Matt Hancock called for people to act responsibly but said the majority of people were abiding by the guidelines.
The announcement of the new rules, shortly after 16.00 GMT on Saturday, prompted a rush to London’s railway stations.
By 19.00, there were no tickets available online from several stations including Paddington, Kings Cross and Euston.
