Samajwadi Party leader Abu Asim Azmi on Monday supported RSS's stand to protect north Indians against any discrimination in Mumbai. "I welcome RSS's statement to protect north Indians against any discrimination in Mumbai. I think now BJP should also speak openly about it," Azmi told reporters here on Monday. Azmi criticised move of Raj Thackeray-led MNS to teach Marathi to north Indian taxi drivers. "They cannot force any language on the people. I would approach the court against it," he said. On losing Bhiwandi seat in the Assembly by-polls last month,Azmi said Congress divided Muslim votes and Shiv Sena won the seat. Azmi's son Farhan had contested from the seat.
