There is a tanker drivers' strike underway in Portugal. It affects the whole of the country, but the Beeb does pick out the Algarve for special mention re the tourist industry.

The tanker drivers are reputedly 'specialists' for driving dangerous cargoes. I haven't a clue as to the driving qualifications of the police and soldier replacements.
I can attest to the existence of long queues at petrol stations in Lagos, just to get 15l of fuel.
Sines is about halfway between the Algarve and Lisbon. I have never visited. It looks quite picturesque, not refinery territory.
We are now being told that the tanker drivers strike has been extended from 2 days to 10.
There is nothing coming through about whether there is a contingency plan, eg for emergency services (police, ambulance, fire), hospitals, electricity, food deliveries to shops and supermarkets, removal of rubbish.
I've got no idea what is happening with bottled gas, which is in widespread use on the Algarve. Block 6 seems to have a giant gas tank in its car park.
Likewise, I've got no idea if taxis and buses get special treatment.
August is normally a month in which public services shut down and people go on holiday. Hmmm. Maybe the tanker drivers are topping up sun tans?
