British holidaymakers are bracing for 'unprecedented' anti-tourism protests across the Canary Islands this weekend.

Hundreds of thousands of fed-up locals are set to take to the streets on Sunday over what they claim is an 'excessive' tourism model.

Under the slogan 'Canarias tiene un limite' (The Canaries has a limit), the demonstrators will gather from 11am on the islands of Tenerife, La Gomera, Gran Canaria, El Hierro, Lanzarote and La Palma.

'Solidarity protests' will also take place in various cities on the mainland, including Madrid, Valencia and Barcelona.

Activists believe the current tourism model is 'unsustainable' and pushing the islands toward collapse.
