The plight of the Windrush families and their British naturalisation is a topic quite close to my heart.
My father was born in India, you see. When WW2 broke out, he came to Britain, joined the RNR and as a ship’s doctor had quite a bad war in the Pacific, North Atlantic and Mediterranean. He held a British passport and settled as a GP in Bermondsey once the war ended in 1947. He obtained British naturalisation without difficulty, because he was a British subject and that did not change until the immigration act of 1948.
