Gibraltar flag flies over the Foreign Office

The flag could have been seen by many as the Paralympic Parade took place along there when thousands crowded central London.

The government of PM David Cameron has decided that the flags of each UK Overseas Territory will be flown over the FCO one day every year, to mark a significant day in each of their respective histories,” said an F&CO spokesman.

“I send my greetings and best wishes to all Gibraltarians ahead of Gibraltar National Day. It is a day to celebrate the people of Gibraltar, their community and identity. It is fitting that Gibraltar’s flag should be flown annually in London to mark this occasion,” said David Lidington, who has responsibility for the EU and Gibraltar.

Mark Simmonds, responsible for British Overseas Territories, said he was pleased that the FCO will be “celebrating this new era of positive engagement between the UK and the Territories by flying their flags over our building in London. The Government is determined to show our commitment to this relationship in a year which has seen a number of important landmarks, including the publication of the White Paper”.
