Spain has given an assurance there will be no repeat of the incident in which officials on the border with Gibraltar searched a British diplomatic bag, the Foreign Office has said.
The incident, which took place on Friday, was described by a Foreign Office spokesman as a "serious infringement" of international diplomatic protocols.
In our protests we requested an urgent explanation of this incident from the Spanish Government and sought assurances that there will be no further interference with the UK’s official correspondence.
We have now received that explanation from the Spanish and have been assured that we will not see a repeat of these actions.
