British tourists are threatening to boycott Spain after a new daily rule was introduced, which could cost families thousands to holiday.

Several new regulations have been introduced since the UK’s departure from the EU which affect Brits travelling to Spain.

The UK is considered a ‘third country’ following Brexit so visitors must prove they have enough money to last them the duration of their stay.

Holidaymakers must prove they have £98 per person per day of their trip – meaning a family of four visiting for a week must have at least £2,740.

Advice from the UK Foreign Office confirms: “If you enter the Schengen area as a tourist, you may need to provide additional documents at the border.

“As well as a valid return or onward ticket, when travelling to Spain you could be asked to show you have enough money for your stay.”

The chances of being questioned about your funds is thought to be extremely low due to busy Spanish airports in peak seasons wanting to avoid congestion in the border control line.

But the risk is enough to put off visiting, with one person on social media writing: “If the country would stand together and boycott Spain in favour of other Mediterranean countries, within three months they would be begging us to come back. 17 million visitors is a lot of money to the Spanish economy.”

A second agreed: “Stop going they’ll soon stop it. Simple. There’s bags of other places, Greece, Turkey, Malta, Italy you name it… and cheaper too.”

This comes as popular holiday destinations across Spain fight against over-tourism, with tens of thousands in the Canary Islands taking to the streets last weekend to protest the “unsustainable” numbers of visitors.

Activists have said that their home towns “have a limit” and that the huge amounts of tourists that descend in the summer are pushing locals out and have forced them to rely on seasonal work.
