And an Italian job getaway is seeing 10,000 Brits in Italy hit by trebled flight prices as they dash back to the UK before 4am tonight to avoid a two-week self-isolation.British Airways flights from Rome to London cost £276 today but £84 next Saturday.

Sarah Crutchley tweeted: “BA, I'd like a refund for a flight to Italy now its on the quarantine list.” Anna Cusano said: “I'd planned to go to Italy for half-term. It's really disappointing.”

Which? Travel editor Rory Boland said: “Holidaymakers with trips to Italy booked face the stress of trying to claw money back from airlines and travel providers.”

Rellis tweeted: “I’m in Italy and have a flight back on Sunday. I have a new job starting next week so can’t quarantine for 14 days – but how can I get home before 4am Sunday?”

Frankie Onoroise wrote: “I have to go back to work when I'm back from Italy. Who will pay my bills while I quarantine?”

Families are going Greek for half-term instead – with a 1,000 per cent surge in searches for holidays after almost all of Greece's islands were put back on the safe list, Travelsupermarket said.

Bargain week-long holidays cost from just £228 per person with TUI. Travelsupermarket's Emma Coulthurst said: “Brits want sun so are opting for Greece.”

It will be the last overseas holiday until next summer for most, with Europe's ski season up in the air and set to run at much-reduced capacity. UK half-term staycations are being hit by a rash of cancellations, hammering the crisis-hit UK tourism industry.

New tier rules ban millions from taking breaks in higher-tier areas – and overnight trips with family or friends who live in separate households. The Government said: “People should avoid staying overnight in another part of the UK if they are resident in a ‘very high’ area – and avoid staying overnight in a ‘very high’ area if they are resident elsewhere.”
