On 9 December 1920, at Lisbon, the Government of His Britannic Majesty and the Government of the Portuguese Republic signed the Agreement relating to the Suppression of the Capitulations in Egypt. The authentic text is in French; the British Treaty Series 1921 No. 23 (Cmd. 1553) also prints an English translation. The plenipotentiaries were Lancelot D. Carnegie, His Britannic Majesty's Minister, and Domingos Leite Pereira, Minister for Foreign Affairs. The preamble: the moment is opportune to give full effect to the special situation of Great Britain in Egypt and to replace the regime then in force for Portuguese subjects. Ratifications were exchanged at Lisbon on 29 September 1921 (Article 7). The League of Nations registered the instrument on 12 December 1921 (volume 7, pages 258–261).

Article 1: Portugal, having recognised the protectorate in Egypt promulgated by Great Britain on 18 December 1914, renounces in her favour all the rights and privileges which she holds in Egypt under the Capitulations. Article 2: from the coming into force of the new judicial system in Egypt under the authority of Great Britain, the Portuguese Consular Courts will cease to sit, except to dispose of current proceedings. That is not an abolition at the exchange of ratifications, but from the new judicial system.

Article 3: Portuguese nationals shall enjoy in Egypt, as regards public liberties, the administration of justice, private rights — including landed property and mining rights — the liberal, industrial and commercial professions, and taxes and duties, the same treatment as British nationals. Children born in Egypt of a father who is a Portuguese national enjoying there the privileges accorded to foreigners shall be entitled to Portuguese nationality; they shall not become Egyptian subjects.

Article 4: Consuls-General, Consuls, Vice-Consuls and Consular Agents of Portugal in Egypt shall enjoy, from the closing of the Consular Courts, the same immunities as in Great Britain. They shall continue to exercise, in the interests of private persons, so far as is consistent with the laws of Egypt, all their non-judicial functions under the same conditions as formerly. Article 5: pending the conclusion of special agreements relating to Egypt or between Portugal and Egypt, the treaties in force between Great Britain and Portugal will apply in Egypt. In the execution of the treaty of 17 October 1892 and the protocol annexed, relating to the extradition of criminals, the prohibition in Article 3 on extraditing nationals of the High Contracting Parties shall apply, in the case of refugees in Egypt, to the subjects of His Highness the Sultan as well as to all British nationals. The import and export regime between Portugal and Egypt shall not be altered unless twelve months' notice has been given; the clause does not limit modifications applicable to all other countries without distinction.

Article 6: Portugal agrees that, subject only to the unanimous consent of the Powers concerned, all the rights and duties of the International Quarantine Commission in Egypt are transferred to the Anglo-Egyptian authorities. Article 7: ratification; the exchange at Lisbon as soon as practicable. Done at Lisbon, with the seal of their arms. Egypt is not a party to this bilateral instrument.
