In 1834, Fevzi Pasha was assigned to lead the Ottoman delegation which negotiated the Treaty of Saint Petersburg with the Russian Empire.[3][4] He was subsequently implicated in the Churchill affair, a diplomatic crisis between the Ottoman Empire and the United Kingdom. The crisis began when British journalist William Nosworthy Churchill was imprisoned in the Imperial Arsenal after accidentally wounding a local child with his gun while out hunting in Kadıköy. Upon being notified of Churchill's imprisonment, British ambassador Lord Ponsonby demanded his immediate release from prison. The Ottoman Minister of Foreign Affairs, Akif Pasha, initially rejected Ponsonby's demand but changed his mind upon being informed that Churchill had been brutally assaulted by a local mob. The order to free Churchill was conveyed to Fevzi Pasha, who rejected it citing the lack of an official brief from the ministry, as well as the uncertainty of the Churchill's condition, which would influence the decision to press charges against him.
Lord Ponsonby subsequently sent a note to the Ottoman government on 10 May 1836 stating that Britain did not recognize Akif Pasha's ministership, and separately authored a report on 15 May 1836 to the British government in which he claimed that both Akif Pasha and Fevzi Pasha had received Russian bribes in relation to the Treaty of Saint Petersburg. On 27 May 1836, Lord Ponsonby held an audience with Koca Hüsrev Mehmed Pasha, a rival of Fevzi Pasha, where he conveyed the desire of the British government for the removal of both Akif Pasha and Fevzi Pasha from their offices. Whereas Akif Pasha was forcibly retired, either due to or with the pretext of his illness, Fevzi Pasha was promoted to the rank of Kapudan Pasha by Mahmud II on 10 November 1836. Academic Nedim İpek suggests that Lord Ponsonby's attempts to remove Fevzi Pasha was primarily motivated by a desire to curtail the increasing levels of Russian influence over the Ottoman Empire following the 1829 Treaty of Adrianople and 1833 Treaty of Hünkâr İskelesi.[5]
