Manuel Marquez, 55, a delegate of the Association of Spanish workers in Gibraltar (ASCTEG), holds a sign to show drivers waiting in line to enter the British territory of Gibraltar at its border with Spain, in front of the Rock (rear), a monolithic limestone promontory, in La Linea de la Concepcion, southern Spain September 1, 2013. Spain wants to resume bilateral talks with Britain as soon as possible over the sovereignty of Gibraltar, Spanish Foreign Minister Jose Manuel Garcia-Margallo wrote in the Wall Street Journal late last month. A diplomatic war of words over the British Mediterranean enclave began in July when it built an artificial reef in disputed waters using concrete blocks, which Spain says restricts access for its fishermen. Spain lays claim to the territory, with a population of just 30,000, which it ceded to Britain by treaty 300 years ago. Spain has recently tightened border controls and threatened to take further action, including a 50 euro ($67) border levy. The sign reads, "For one worthy border of Europe".
