The flashpoint is a proposed €4 billion ($4.7 billion) development — described by Prime Minister Edi Rama as an "extraordinary investment" — on Sazan Island and the protected Vjosa-Narta coastal wetlands in southern Albania. Ivanka described it in dreamy terms on a recent podcast.

"It's an unbelievable, beautiful, 1,400-hectare private island in the middle of the Mediterranean," she told host David Senra. "We swam to the island, we went on a hike, barefoot all the way up to the top, and we were just captivated."

She did not mention the protests.

On the ground in Albania, the mood was rather less romantic. Anadolu Agency reported thousands gathering in Tirana under the slogan "Albania is not for sale." TV Klan presenter Leftioni Peristere flagged AFP wire coverage of the demonstrations, which have now stretched into a fourth consecutive day — with police firing water cannons at crowds that included children.
