HC Deb 13 September 1939 vol 351 c620
3. Mr. Price

asked the Prime Minister whether any inquiries have been made of the Turkish Government if permission will be granted to allow allied warships into the Black Sea should necessity arise?

The Under-Secretary of State for Foreign Affairs (Mr. Butler)

The circumstances in which warships may pass through the Straits in every contingency are governed by the Montreux Straits Convention, of which His Majesty's Government are one of the signatories and to which I would refer the hon. Member.
