Packed London Tube trains are the latest symbol of the UK's confused coronavirus response

London (CNN)As thousands of people returned to work across England on Wednesday morning, images of packed London Underground trains have sparked fresh criticism of the government's strategy for easing the country's seven-week lockdown.

Photos circulated on social media of commuters crowding onto congested train platforms, some without masks, or piling into crowded double-decker buses, raising questions about how Prime Minister Boris Johnson plans to get the country back to work without causing a second wave of coronavirus infections.

Johnson also suggested that people should get to work by car, bike or on foot if possible.
      Johnson's speech, which seemed to imply that people would be allowed back to work the following day, was criticized by the leader of the opposition, who said it was "quite a thing to spring on people for tomorrow morning," and the chief of one trade union who described the messages as "both confusing and disbelieving."

And while the government on Tuesday advised people to wear masks in enclosed spaces, they are not mandatory.
        At Wednesday afternoon's weekly session of Prime Minister's Questions, Johnson expressed concern at the number of commuters using London's public transport network, and
