Yusuf Kemal Bey, who had served in important positions during the National Struggle, was appointed as the London Representative of the new Turkish Republic in November 1923. Since the Lausanne Peace Treaty, which Turkey had ratified in the August of the same year, was not ratified by the United Kingdom, ordinary diplomatic relations between the two states had not yet been established. Therefore, he was appointed as a representative, not as an envoy or ambassador. However, he represented Turkey in Britain as a diplomatic representative and conducted bilateral relations.

Yusuf Kemal Bey took office at a time when Turkish-British relations were tried to be re-established. The Treaty of Lausanne and the Mosul Question were the most important subject matters between the two countries. Therefore, he concentrated his activities mostly in these topics. At the same time, he established contacts with political, bureaucratic and social circles of England. He tried to represent Turkey in the best way possible. After intense times, he resigned from his post in May 1924. Because pursuant to the 1924 Constitution, no other official duty could be carried out together with the deputyship and he chose to serve in the parliament. Yusuf Kemal Bey continued his activities in the parliament and worked in fields such as politics, law and education in the following years.
