Mr Singh launched his attack in a fit of anger after the minister dismissed his interjections over the recent acquittal of senior Congress politician Jagdish Tytler, who had been accused of leading Hindu mobs in communal attacks on Sikhs following the assassination of Indira Gandhi by her Sikh bodyguards. They had killed her in protest against her decision to order an Indian Army attack on Amritsar's Golden Temple, the centre of the Sikh faith.
