Shimla: Himachal Pradesh Public Works Department Minister Vikramaditya Singh announced his resignation on Wednesday
The announcement by the Congress MP exposed weaknesses in the party, which lost its only Rajya Sabha seat to the BJP on Tuesday and appears to be scrambling to hold its members together to prevent the government from falling.
The election was spoilt for Congress due to cross-voting by some of its members.
Vikramaditya Singh is the son of former Himachal Pradesh chief minister Virbhadra Singh and is an MLA from Shimla Rural.
