Even as the Indo-US nuclear deal is stuck in what Prime Minister Manmohan Singh calls "domestic politics', External Affairs Minister Pranab Mukherjee is headed for uranium-rich Australia for a three-day visit beginning this Saturday. The visit, between June 21 and 24, will be important from India's nuclear point of view since Australia is a key member of the Nuclear Suppliers' Group (NSG). The fact that the UPA-Left committee on the nuclear deal will meet on June 25, immediately after Mukherjee's return, makes its timing even more significant.
