In a blow to the Congress-JDS coalition in Karnataka, two MLAs Tuesday withdrew support to the government headed by H D Kumaraswamy.
In separate identical letters, available to the media in Bengaluru, the lawmakers said they were withdrawing support extended to the coalition government of the Congress and the JDS with immediate effect.
The MLAs, who are now staying in a Mumbai hotel, requested the governor to take "necessary action."
Both the Congress and the BJP have been accusing each other of trying to lure legislators.
The BJP MLAs are presently camping in Gurgaon, amid reports that some Congress and Independent MLAs are staying at a hotel in Mumbai.
With the loss of 2 MLAs, the strength of the ruling coalition is down to 118 in the 224-member Karnataka Assembly. With 104 lawmakers, the BJP is far short of majority.
