Legal threat to Spain as Gibraltar row deepens
Britain is considering legal action against Spain over the continued imposition of additional checks at the border with Gibraltar, Downing Street has said.
A No 10 spokesman said it was looking at the "unprecedented step" after the Spanish government failed to lift the extra controls over the weekend.
"We are now considering what legal action is open to us," the spokesman said. "This would be an unprecedented step so we want to consider it carefully before making a decision to pursue."
The move comes amid a worsening row over the the construction of an artificial reef by the Gibraltarian authorities which Spain claims will destroy fishing in the area.
Madrid responded by beefing up border controls, leading to lengthy queues, and suggesting that a €50 (£43.30) fee could be imposed on every vehicle entering or leaving Gibraltar via Spain.
