Boris Johnson returns to work

He was photographed in the back entrance of Downing, where he smiled in front of a security guard before entering.

Johnson returns to Westminster facing an increasing government demand to publish an exit strategy from the country's impasse due to the coronary.

The British prime minister was affected by the coronary, and his task was carried out by Foreign Secretary Dominic Raab for nearly three weeks.

Johnson, 55, was released from St Thomas Hospital in London two weeks ago.
