Is there a British Embassy or Consulate in Cape Verde

There isn't a British Embassy or British Consulate in Cape Verde. There is an Honorary Consul on Sal Island who can be contacted in case of serious danger, death, imprisonment and other similar problems. However, British Nationals should seek other information from the Foreign and Commonwealth Office before travelling to Cape Verde.

There was a British Embassy Booklet produced for Cape Verde in 2012 (out of date), but it will provide some additional information that you may find useful. Click here for more info:
