The chargé d'affaires at the British Embassy in Ankara, Michael Stewart, directly implicated Menderes' Demokrat Parti in the execution of the attack. "There is fairly reliable evidence that local Demokrat Parti representatives were among the leaders of the rioting in various parts of Istanbul, notably in the Marmara islands, and it has been argued that only the Demokrat Parti had the political organisation in the country capable of demonstrations on the scale that occurred," he reported, refusing to assign blame to the party as a whole or Menderes personally, however. The Foreign Office pointedly underscored the fact that British citizens were also victims of the attack.
