In the February 27 polls, the UDP got 11 seats in the 60-member Meghalaya Assembly (elections held in 59 seats) and after the announcement of the result, the tribal based party became an ally of NPP-led Meghalaya Democratic Alliance (MDA) government. The UDP, NPP and BJP, who fought the February elections against each other, are now partners of the MDA government, headed by Chief Minister Conrad K. Sangma, who is also the national President of the NPP. /IANS
