Maharashtra Navnirman Sena chief Raj Thackeray will arrive in Calcutta this evening to meet Bengal chief minister Mamata Banerjee at state secretariat the next day.

'They are likely to discuss electoral reforms, demand for return to the ballot paper and the political situation in the country,' a source close to the MNS chief told PTI.

Trinamul sources said Raj had called up Mamata and expressed his desire to meet her for discussing the issues.

Mamata, a strong advocate of electoral reforms and return to the ballot paper, had accused the BJP of winning the 2019 Lok Sabha polls by tampering EVM machines.
