GIBRALTAR / UK (Agencies) Although the subject is not high on British Foreign Secretary William Hague's list of priorities, he will have to broach it when he meets his Spanish counterpart, José Manuel García-Margallo, next Tuesday in London. The subject, of course, is the dispute about fishing rights in the waters surrounding Gibraltar, which are claimed by Spain. Another thorn in the Spanish side is the visit to the Rock by Prince Edward in July, which Spain sees as 'provocation'. It was Hague's idea that the two should discuss the state of bilateral relations, but the last couple of weeks of tensions, plus a build-up of incidents between the Royal Gibraltar Police and the Guardia Civil that now seemed to have calmed down, have seen Gibraltar creep into and up the meeting's agenda. Britain is also expected to make a formal complaint about the long queues resulting from border controls on the Spanish side.
