This was explained in a talk that Andrew Whitehead gave this week at the University of Kashmir, with more than a hundred faculty and students present. The talk focussed on 'Freda Bedi in Kashmir' - the Bedis lived in Srinagar from 1947 to 1952 and had an association with the state, and particularly with Sheikh Abdullah's National Conference, from the late 1930s.
The talk has been reported on the Outlook website - here's the link: http://www.outlookindia.com/website/story/sheikh-abdullahs-new-kashmir-manifesto-was-a-cut-and-paste-of-stalins-constituti/298388
