With the continent sweltering under a heatwave nicknamed Lucifer, tempers have been boiling over, too, as a wave of anti-tourism protests take place in some of Europe's most popular destinations. Yet, as "tourism-phobia" becomes a feature of the summer, the World Tourism Organisation (UNWTO) has defended the sector, calling on local authorities to do more to manage growth in a sustainable manner.
The focal point for much of this has been Spain, which had a record 75.6 million tourists last year, including 17.8 million from the UK. In Barcelona, where tensions have been rising for years over the unchecked surge in visitors and impact of sites such as Airbnb on the local housing market, Arran, the youth wing of the radical CUP (Popular Unity Candidacy), have been filmed slashing the tyres of rental bicycles and a tour bus. An Arran spokesperson told the BBC: "Today's model of tourism expels people from their neighbourhoods and harms the environment." Spanish prime minister Mariano Rajoy described the group as "extremists".
