On 30 June 1947 (one and a half months before the independence of India), there was a discussion in the UK House of Commons about Anglo-Indians and Europeans (alternative link):
Mr. Gammons asked the Under-Secretary of State for India what reply he
has sent, or proposes to send, to the request made by the Anglo-Indian and domiciled European communities of India that they should be established in a homeland of their own and that, in particular, facilities should be provided for them to settle in the Andaman and Nicobar islands.
The Under-Secretary of State for India (Mr. Arthur Henderson): A representation has been received from a body called the Britasian League of Calcutta, but it is not considered that any such scheme is practical or desirable, particularly in view of the policy of the Anglo-Indian Association, which regards this scheme as impracticable.
Mr. Gammans: Do the Government accept in principle the responsibility for finding a homeland for the Anglo-Indian community, for whom we have a special responsibility, if they do not desire to remain either in Hindustan or Pakistan?
Mr. Henderson: That is a hypothetical question. The only information which we have is a statement made in February of this year on behalf of the Anglo-Indian Association, that while it is not against individuals emigrating if they choose, it will not officially sponsor any such idea.
Note that there is a typo in the document: "Mr. Gammons" should be "Mr. Gammans".
