Imran has actually accepted Sita White as his daughter in principle but for reasons (cultural and religious sensitivities) which are quite obvious to any sane person he cannot say so in public. There was a 10-12 page spread in Hello magazine in late-90s with pictures of Imran and Tirian when Imran went to visit Sita White in USA. Tirian had just received a prize (for high achievement in maths) from Bill Clinton.
