Gibraltar border delays end after Foreign Office involvement
29 July 2013 Last updated at 14:08 BST
The Foreign Office has raised concerns with Spain about long delays caused by a rise in vehicle searches at its border with Gibraltar.
At the weekend - as temperatures soared - motorists had to endure queues of up to six hours - waiting for documents and vehicles to be checked.
There are reports the delays could be linked to a fishing dispute between Spain and Gibraltar.
