The Beebs take on what is happening in Paris - maybe the 50-pager later today will specify masks for us too?

In the French capital, metro and bus services are operating, though only every second seat can be used and masks are compulsory. The public transport network is less crowded than feared as commuter traffic has remained light.
Car traffic is much less dense than in normal times, and with bars and cafés shut - and no tourists to speak of - the city still feels unusually quiet, says the BBC's Hugh Schofield in Paris.
On the metro and suburban commuter lines, passengers need an authorisation from their employer if they travel during rush hour - and in general, it has been possible to maintain social distancing.
The head of the Paris public transport operator RATP, Catherine Guillouard, noted people were mostly wearing masks around the network - which "even goes beyond 95% in some places".
But on some parts of the system, there have been incidents of commuters struggling to maintain social distancing.
There was some congestion first thing this morning on line 13 of the metro network after water leaks at two stations caused traffic delays, leading to carriages being overcrowded.
And at some RER stations, commuters were also unable to observe social-distancing rules.
