One can imagine having favorable trade and immigration deals with India could be really great for IT in the UK.
It looks like the WTO rules could be expensive:

An added kicker is that the UK currently has no trade negotiators because they haven't had to negotiate their own deals in a couple generations. They'll need to get up to speed very quickly with a very large number of negotiators. You don't usually have to negotiate all your agreements at once!
I concede to greater minds than mine, but those minds are estimating something in the range of a 2-3% impact in the long term, nothing drastic. I'm unclear about the reasoning behind the doom-and-gloom.
To be fair, a 2-3% impact is huge in the scheme of things. Especially in the current slow-growth environment. As a comparison, in the US February 2008 to February 2010 there was a 5.1% GDP contraction and that event will be in history books for centuries.
