Union ministers Pralhad Joshi and Narendra Singh Tomar are likely to visit Gujarat today as the BJP's central observers to a meeting of the legislature party to choose the new chief minister following Vijay Rupani's resignation, sources said. Mr Rupani's resignation came 15 months before the election to the 182-member Assembly that is due in December 2022. He is the fourth chief minister to demit office in BJP-ruled states during the coronavirus pandemic.
