Unresolved Gibraltar issues endanger Brexit plans, warns Spain

A rocky peninsula is again emerging as a big hurdle standing in the way of Britain’s exit from the EU.

Spain’s Prime Minister Pedro Sanchez is demanding that the Brexit agreement clarify that the status of Gibraltar will be directly negotiated between Madrid and London.

UK-controlled Gibraltar voted overwhelmingly to stay within the EU and, while residents appear to be resigned to the impending Brexit, they and large numbers of Spanish workers employed across the border still face an uncertain future.

Al Jazeera’s Natacha Butler explains why Spain may torpedo a crucial Brexit summit this weekend.
