Feb. 17 (Bloomberg) -- Prime Minister David Cameron said the U.K. and France will invest together in an unmanned drone program as part of their strategy of defense cooperation.

“It’s partly about our capacity, investment we’re going to make in our drone program,” Cameron said at a joint press conference in Paris with French President Nicolas Sarkozy. He said the two countries will be “cooperating over the most sensitive dossiers of all, including nuclear.”
