A Delhi court has directed CM Sheila Dikshit to appear in person before it in a defamation case filed by her against city BJPchief Vijender Gupta. Dikshit filed the case against Gupta for allegedly using "uncivilised" language in hoardings put up prior to the civic polls. She told the court that she had sent legal notices to Gupta after the civic polls, but the BJP leader did not apologise.
