The House of Commons was moved by Roebuck to reverse the rebuke, which it did on 29 June by a majority of 46, after having heard from Palmerston on 25 June. This was the most eloquent and powerful speech he ever delivered, wherein he sought to vindicate not only his claims on the Greek government for Don Pacifico, but his entire administration of foreign affairs.
