I suspect the UK's interest in India at present is focused on winning defence contracts, which are currently dominated by Russia and Israel. One would hope that the UK saw something more strategic as they are clearly one of the global powers of the future.
India has been on everyones radar since 1997 when they were first seriously identified as an emerging superpower, unfort they fell off the screen when they copped a financial beating that and subsequent year and it set them back.
India has a love hate relationship with the UK, they highly value the officer development and regimental/force structure across all services, but then you also come across the issue of anti-colonialism which still has some legs in some quarters. The india/pakistan issue also slips into play here and UK cops a flogging for the separation and kashmir etc... its not a mater of whether its accurate, it just "is".
Ironically within all the twists and turns of legacy british attitude, russian kit and a sense of obligation in some quarters to stay with the russians, they do seem to have a closer relationship bubbling below the surface than they let on - but the more robust members of the Jai Hind brigade are happy to bring that undone.
I spent a few years working on projects in India, and my "throw away" experience was that at a military and trade level they wanted to up their relationship with the west. I started stating this on some of the indian forums (Proton and BR) and at the time got a complete belting by the pro Russians and Jai Hinds. I even stated at the time (3-4 years ago) that the Indians intended to start with non "combat" buys such as ASW aircarft to replace their Ilyushins and then progress to combat platforms. That has basically come to pass
It was inevitable that the UK would lift its profile with India, esp as they've seen that the americans have been able to make inroads into territory where they probably thought that the Indians would play them mercilessly.
as a sidebar - the odds are looking to shorten in favour of a Typhoon sale to India
