On 31 May 1938, Bonnet refused a British request for an Anglo-French "démarche" to Beneš demanding concessions to the Sudeten German "Heimfront", but promised to commit the French Minister in Prague, Victor de Lacroix, to do more to pressure the Czechoslovaks. In his instructions to Lacroix for the "démarche", Bonnet instead merely asked for more information and stated: "The information that you have transmitted to me on the state of the negotiations between the Prime Minister and the representatives of the Sudetens does not allow me to pronounce as fully as the British Government believes itself able to do on the character and substance of M. Henlein's proposals... I ask you, therefore to obtain urgently the necessary details on the proposals submitted to M. Hodža..." The British discovery of Bonnet's instructions, which Lacroix inadvertently revealed to the British Minister in Prague, Sir Basil Newton, led to much Anglo-French recrimination.
