Love it when I'll-informed people are rude to other posters yet have it completely wrong themselves...
Just been watching BBC news, they have just been talking about Portugal as I came across this thread.
This news story seems to be exactly what was said on the BBC news just now.
Summary:
no decision from Portugal yet, their 'state of calamity' has been extended to May 30th. Personally I'd be worried if I had a booking for Portugal before then.
They are considering allowing a limited number of fans to go for the football, subject to tight controls, but not yet announced.
