"Governing a state as large as Uttar Pradesh will not be as easy as governing a mutt," said the Sena which has been at loggerheads with the BJP despite being the junior partner at the centre and in the Maharashtra government.
The Uddhav Thackeray-led party, which was left with heartburn after it was denied the Deputy Chief Minister' post by the BJP in 2014, also took a dig at its ally over appointment of two Deputy Chief Ministers in UP, saying it was aimed at keeping Adityanath "free to perform his religious duties".
"By appointing two Deputy CMs in UP, Yogi Adityanath has been left free to do religious duties," Sena said in an editorial in the party mouthpiece 'Saamana'.
"Rather than performing religious duties, Adityanath should focus on delivering good governance and development. Governing a state as large as Uttar Pradesh will not be as easy as governing a mutt," the Sena said in a reference to Gorakhpur mutt which is headed by Adityanath.
The Adityanath Government, which was sworn in on Sunday, has BJP's Uttar Pradesh unit chief Keshav Prasad Maurya and party's national vice-president Dinesh Sharma as deputy chief ministers.
The Sena asked Adityanath to remember the "imbalance" created in Madhya Pradesh after the then Chief Minister and BJP leader Uma Bharti "focused more on religious activities than good governance".
