In the meantime, Peter Shore, the then Secretary of State for Trade, had conducted a review of the government's aviation policy and in 1976 announced a new "spheres of influence" policy that ended dual designation for British airlines on all long-haul routes. As a result of this new aviation policy, BA and BCal were no longer permitted to run competing scheduled services on the same long-haul routes and the latter was forced to withdraw from the London—New York and London—Los Angeles routes, resulting in the suspension of BCal's Gatwick—JFK and Gatwick—Los Angeles licences. The same year, Edmund Dell, Peter Shore's successor, renounced the original Bermuda air services agreement of 1946 and initiated negotiations with his US counterparts on a new air services agreement, which resulted in the Bermuda II treaty of 1977.
