I understood the general opinion on face masks was that it was very doubtful they did any good in stopping the virus.
So, is this yet another about turn? Where am I supposed to get a face mask? I thought they were supposed to be so rare they were going on the open market for 6 toilet rolls and a packet of pasta?
I agree it is another about turn, but policies change as more knowledge becomes available, as Maiden Stone said.
However Grant Schapps did try to make it clear that the 'science' did not fully support the wearing of face masks/coverings as a way to limit spread of this coronavirus. Indicating that the policy has not been changed for scientific reasons.
There is no agreement on effectiveness. They have been described as "a potentially useful extra tool". Most important are physical distancing and handwashing.

An article in today's "Independent" reports differing views. Quotes Professor Anthony Costello, UCL Institute for Global Health "there is no perfect evidence"; 2 reviews published by "The Lancet" and the Royal Society showed face coverings can help reduce viral transmission on public transport.

Scottish SAGE recommended face coverings 28th April. See my reply 21.
Experts give their opinions. It's up to politicians to consider advice and decide whether to apply it to the current situation.
