"I have the remote control of politics and the remote control will continue to remain with me," Mr Thackeray said in an editorial in 'Saamana", published on his birthday.
Also published in the party mouthpeice, is a letter from the chief addressing the Shiv Sainiks.
“I don"t have the energy I had earlier due to old age. I have just come back from illness, so won"t be able to meet you at Matoshree....but I am close to you from my heart. You have Uddhav. He will greet you at Matoshree," Mr Thackeray told Sainiks.
Matoshree is Thackeray's Bandra residence, where Sena workers gather every year on this day to greet their chief.
Speaking about his party, Thackeray wrote, “The sapling (Sena) I planted 45 years ago has grown into a vine, which reached the power centre in Delhi."
He added that 'Marathi manoos" was the centre of “our thoughts and will remain so".
