"The great-grandfather of Duleep Singh and the Great-grandfather of the Thakur were from the same family, but he [Duleep Singh] also adopted them as his sons. Our property was confiscated by British rule. This letter establishes us as the rightful heirs of Duleep Singh and we want to get back his remains and his other belongings to the Golden Temple," Jaswinder Singh Sandhanwalia told The Daily Telegraph on Sunday.
