Dont you just love it when Spain objects to Britains sovereign rule over Gibralter but made them very welcome during WW2.

A Royal Navy warship arrived in Gibraltar on Monday morning, 24 hours after Spanish boats staged a protest in British waters around the Rock as part of the ongoing dispute about the creation of a new concrete reef.

HMS Westminster, which approached the port flanked by two smaller British vessels, is officially visiting as part of a routine deployment in the Mediterranean, but its arrival will be seen as a show of support from London for Gibraltar in its increasingly acrimonious dispute with Madrid.

Spain says the concrete reef will damage Spanish fishermen's interests and it has retaliated by imposing delays at the border crossing. Britain has complained that these measures are disproportionate and it has asked the European commission to intervene.
