Greve has been appointed as group finance director designate. He will join next month and take over from Lynas, who has held the post for more than eight years, on April 1.

BAE said Greve had more than 30 years experience with large multinational organisations in the oil and gas industry across Europe, the United States, South America and Africa.

Last week BAE said improvements in its maritime and combat vehicle operations helped drive a rise in first-half earnings against a backdrop of geopolitical uncertainty that has dampened hopes for a major order from Saudi Arabia.

BAE said that most recently Greve has been the top financial executive responsible for overseeing $20 billion (£16.48 billion) of annual revenue and $1 billion of annual capital expenditure as financial controller of the Wells business at Schlumberger.

He will receive a base salary of 610,000 pounds and can participate in the group's annual incentive and long term incentive plan.
