Carpet dealer Deepak Jaikishian has filed an RM676 million suit against former premier Najib Abdul Razak, his wife Rosmah Mansor and two companies for conspiracy and exerting undue influence on him over three parcels of land near Bukit Raja.

The 180ha piece of land is said to have been the venue of the National Defence Study Centre which was supposed to have been built there in 2007.
