Could a British Menorca base have aided Malta?

Would a retained British base at Menorca have been useful in supporting Malta?

It could have been useful, but only with significant peacetime investment and forces to defend it.

A British Menorca could have helped Mediterranean operations much as Crete could. Its usefulness would depend on retaining the island long enough to develop facilities and defenses in peacetime. Such a base would consume Royal Navy and RAF resources rather than providing a free strategic advantage. Its proximity to the Spanish Civil War might nevertheless have encouraged Britain to fortify it well before the world war.
