If one shareholder [GoK in this case] sell their shares, then that's not a rights issue... it would be a secondary offer and the shares would be offered to everyone, not just to the existing shareholders.
GoK will not renounce its rights, rather it will sell them in the NSE to any willing buyer at some premium. That's the way it can make money from its converted shares....and still keep them.
But at then of the process, GoK's percentage holding in KPLC will be diluted even though their total number of shares will remain the same.
Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.
