He was a Congress corporator of ward no. 17 (A) of Nashik Municipal Corporation and had joined BSP before the elections.
Patil, who was defeated by Shiv Sena candidate Hemant Godse in the LS polls, joined BJP yesterday in the presence of party state unit vice-president Dr D S Aher and MLA Girish Mahajan and other party leaders, Savaji said.
Patil is likely to contest by-polls on a BJP ticket from ward no. 17, which has fallen vacant after he had joined BSP. By-polls is likely to be held this month, he added.
