Who coined the term ' pakistan'?

Rahmat Ali had already voiced his idea for an independent Muslim state on the subcontinent before he moved to Britain, it was here that he would publish his pamphlet Now or Never: Are We to Live or Perish for Ever? (1933). In this pamphlet, issued on 28 January 1933, he made an appeal 'on behalf of the thirty million Muslims of PAKSTAN, who live in the five Northern Units of India - Punjab, N. W. F. P. (Afghan Province), Kashmir, Sindh and Baluchistan, embodying their inexorable demand for the recognition of their separate national status, as distinct from the rest of India, by the grant of a separate Federal Constitution on social, religious, political and historical grounds'. According to one source, Rahmat Ali had already coined the word in late 1932, while travelling on top of a bus (route 11) in London (see Aziz, Rahmat Ali, p. 89).

The name of the country was coined in 1933 as Pakstan by Choudhry Rahmat Ali, a Pakistan Movement activist, who published it in his pamphlet Now or Never, using it as an acronym   referring to the names of the five northern regions of British India: Punjab, Afghania, Kashmir, Sindh, and Baluchistan. The letter i was incorporated to ease pronunciation.
