Asserting their "right" for a privileged treatment and differentiation from the common man, around 100 MPs on Friday demanded that they be allowed to have red beacons atop their cars across the country to save them from being challaned by traffic cops. In a petition to Lok Sabha Speaker Meira Kumar and Chairman of Privilege Committee PC Chacko, the MPs cutting across party lines - barring the BJP - also reiterated their demand that they should not be asked to pay toll tax at National Highways. The demand had earlier also been made by a section of Parliamentarians.
