Maharashtra Chief Minister Eknath Shinde on Thursday slammed Shiv Sena (UBT) chief Uddhav Thackeray for breaking his party`s "natural alliance" with the BJP and using the names of Bal Thackeray and Prime Minister Narendra Modi to win elections.

Eknath Shinde, who has set out on a statewide tour in the wake of the NCP led by Ajit Pawar joining the ruling alliance, was speaking at a rally in Thane.
