Lucknow: Uttar Pradesh chief minister Mayawati on Sunday sacked four ministers facing corruption charges in another clean-up act, a day after the assembly poll schedule for the state was announced by the Election Commission.

“The governor has received recommendation of the chief minister to sack four ministers," the principal secretary to governor, G.B. Patnaik said.

The chief minister had not cited any reason for dropping the ministers in her communication to governor B.L. Joshi, officials said.

The four ministers were mired in controversies as they were facing corruption charges. Tripathi is also facing a Lokayukta probe for alleged corruption.

The opposition has been demanding the resignation of the four ministers for a long time.

Mayawati’s action is seen as an attempt to refurbish her government’s image ahead of assembly elections, after being constantly targeted by the opposition parties over corruption charges.
