Ships in four countries were subjected to boycotts and delays on the second day of a week-long European campaign against flags of convenience, the International Transport Workers' Federation (ITF) says. Transport unions held up ships in Portugal, Norway, Croatia and Sweden, the ITF said. It said Norwegian dockers at Narvik boycotted the Leon, a United States-owned 128,000 deadweight tonne (dwt) bulk carrier, delaying the vessel. The Panamanian-registered 29,400 dwt bulk carrier Sharpnes was held up in Leixoes, Portugal while an ITF agreement was negotiated for its Russian crew, the union said. The ITF also said a small German bulker was held up in the Croatian port of Rijeka and a Cypriot-flag general cargo ship was boycotted in Gothenburg, Sweden.
