HOW TO DRAIN A DRAGON
The British overseas territory of Gibraltar has an official population of 32,688. If it were sawn off the Iberian peninsula and reattached to the north side of the Bristol Channel, it would be Wales’s 13th-largest settlement, tucked in between Caerphilly and Pontypridd. At its narrowest point, just north of the airport runway that backs on to its national and only football stadium, it is around 400m wide. With a fair wind, Wayne Hennessey might be able to boot a football right across it.
