Thackeray, the estranged cousin of Sena chief Uddhav Thackeray, said the BJP's claim of the 'party with a difference' is false.
"It is the habit of the BJP to spread all kind of lies. The Maharashtra government claims that it has dug 1.20 lakh wells (to overcome water shortage) and made the state free of open defecation. These claims are false," he said.
Thackeray attacked Union Law Minister Ravishankar Prasad over his statement that prices of fuel are not in the hands of the government.
"Ravishankar Prasad says that the prices of fuel cannot be brought down. If that is so then how could the BJP government in Rajastan manage (to bring) them (down). If Prasad were right then why he and his party had been holding agitations (against fuel price hike) before 2014 polls," he asked.
He said the Narendra Modi government is levying heavy taxes on fuel to recover the losses.
Demonetisation exercise has failed and the economy is severely damaged, Thackeray said, adding that the BJP now has the sole agenda to "fetch donations and win elections".
In 2016, Prime Minister Narendra Modi had announced scrapping of Rs 500 and Rs 1000 currency notes with twin objectives of bringing out black money and clamping down on terror financing.
In its report, the RBI recently said that 99 per cent of the currency in circulation at the time of note ban has returned in the banking system.
In a veiled attack on the prime minister, Thackeray said the head of the country should act like a king and not as a merchant.
On Sena's stand to not support Monday's bandh, Thackeray said, "Sena's stand is that if there works are stuck they oppose the BJP and get the work done. They have nothing to do with the suffering of the common people".
Thackeray accused the BJP government of booking MNS workers on "false charges", which he said would backfire.
Seeking to dispel perceptions about MNS's growing proximity with the Congress in view of the regional party backing the bandh, the MNS chief said the cause is more important than who has given it.
Apart from the MNS, the Nationalist Congress Party (NCP), the the Samajwadi Party, the Peasants and Workers' Party and the Bahujan Samaj Party (BSP) supported the shutdown in Maharashtra.
