In 1886 Naoroji was elected as President of the Indian National Congress.

Naoroji moved to Britain once again and continued his political involvement. Elected for the Liberal Party in Central Finsbury in July 1892, he was the first British Indian MP. He refused to take the oath on the Bible as he was not a Christian, but was allowed to take the oath of office in the name of God on his small book of Avesta. In Parliament he spoke on Irish Home Rule and the condition of the Indian people. In his duties as an MP, he was briefly assisted by Muhammed Ali Jinnah. In 1906, Naoroji was again elected president of the Indian National Congress; Jinnah served him there as a secretary.
