Last week Italy was, again, struggling with the conundrum of mass tourism. One of the country’s most charming seaside towns, Portofino, has just introduced legislation to dissuade tourists lingering for selfies: there will be fines of up to €275 (£243) if they block traffic or pedestrians in two “red zones” of the beautiful bay.

It’s the latest in a series of draconian measures adopted by Italian councils to deal with herds of holidaymakers: there are fines of up to €2,500 for walking the paths above the Cinque Terre (five villages in Liguria) in flip-flops or sandals; you are no longer allowed to eat snacks outside in the centre of Venice or in four central streets in Florence.
