For the first time since it came to power in 2004, the UPA government is faced with the prospect of being reduced to a minority in the Rajya Sabha in April when 59 members are retiring. Election to fill these vacancies is set to reduce the ruling combine to a gasping minority.While it may not affect the functioning or survival of the government, it puts a big question mark on the government’s ability to push through key legislation, especially the contentious ones like the Communal Violence (Prevention, Control, and Rehabilitation of Victims) Bill, Foreign Contribution (Regulation) Bill, etc.That also perhaps explains the magnanimity shown by Congress President Sonia Gandhi in receiving BSP supremo Mayawati at 10, Janpath last week, notwithstanding the fact that the latter has been constantly ranting against the Congress and is set to damage the party’s prospects in Assembly elections this year.The BSP’s support could be crucial for the UPA’s legislation. More so, 10 Rajya Sabha Members from UP will also face elections by November. As it is, the UPA, the Left, Independent supporters and Nominated members with leanings for the ruling combine together account for 118 in a 245-member House. These include NCP-backed Independents PC Alexander and Rahul Bajaj — although they were supported by the BJP too — and Congress-backed Independents Arjun Sengupta and Vijay Mallya. Five members were nominated by the UPA government.
