Trinamool Congress leader Mahua Moitra will approach the Delhi High Court today to challenge a notice asking her to vacate the government bungalow she had been allotted as an MP and warning of "use of force" if necessary, sources have told NDTV. The Trinamool leader, who was expelled as Lok Sabha MP last month on grounds of unethical conduct, will file a writ petition against the eviction notice in the court of Justice Manmohan shortly.
