asked the Prime Minister whether any negotiations, formal or informal, are taking place between His Majesty's Government and the Government of France on the subject of a separate Anglo-French Treaty for the defence of France, in the event of the United States refusing to enter into such a Treaty; and whether an assurance can be given that no such separate obligation will be undertaken by His Majesty's Government in view of the fact that the undertaking of a similar obligation by the United States of America was a pre-condition of the Anglo-French Treaty as laid before the House?
