A floor test is a constitutional mechanism. It is used to determine if the incumbent government enjoys the support of the legislature.
In this procedure, a CM appointed by the Governor can be asked to prove a majority on the floor of the Legislative Assembly of the state.
Will Uddhav survive the floor test?
Rebel Shiv Sena leader Shinde has claimed the support of 50 MLAs, including 10 independent MLAs
On the other hand, Uddhav enjoys the support of 4 ministers and 15 MLAs as of now. Going by the numbers, MVA government has a negligible chance of survival.
