Thanks all for the views. It isn't really an option to keep both and not tell India about it. It's against the laws (and since i'm a solicitor, it could have some repercussions down the road) and boarding a plane in India to the UK requires showing them your visa at multiple points. Since I would only have the passport, it would be pretty easily detectable. There's no visa in the passport as there is a separate biometric card for that, which i'll be required to give up when applying for the British passport.
@Aldav - UK allows dual citizenship so not a problem from that side; only from the Indian side. I (briefly) looked into regaining it once lost, and I THINK it should be straightforward enough...just requires me to be resident in India for a year. Need to investigate that part more though.
@jimbeam - I'll doublecheck, but i'm pretty sure it is only agricultural property. Thanks for pointing that out.
