Standing apart on either side of a strip of red carpet outside Number 10 Downing Street, Prime Minister Boris Johnson and French President Emmanuel Macron demonstrated the unusual reality of international diplomacy in the coronavirus era. Macron's visit to London on Thursday to mark the 80th anniversary of General de Gaulle's call for wartime resistance is one of the most high-profile foreign trips by a head of state since many countries imposed lockdowns to curb the virus. Smiling and turning to face the cameras, Macron held up an arm sideways to check the distance between the two, while Johnson offered his counterpart a slightly awkward thumbs up.
