Sir: The Jamiat-i-Ulema-e-Islam-Fazl (JUI-F) chief, Maulana Fazlur Rehman has said that if certain reservations on the 21st Constitutional Amendment are not allayed, the matter could reach D-Chowk in the shape of a protest. In order to differentiate between the ongoing protests, it will be better to consider re-naming D-Chowk as Diesel-Chowk for clarity. DR IRFAN ZAFAR Islamabad
