Kolkata: Trinamool supremo Mamata Banerjee appreciated BJP veteran L K Advani’s views of extending democratic courtesies to Opposition leaders, stating that all Opposition leaders are not anti-national. In a tweet, she said: “As the seniormost politician, former Dy PM and founding father of BJP, the views AdvaniJi has expressed about extending democratic courtesies is significant.

We welcome his statement & convey our humble regards.” Earlier in the day, Advani broke his silence and wrote in his blog that he never regarded his critics as ‘enemies’ or ‘anti-nationals’. In the piece, he urged the party to “look back, look ahead and look within” and stressed on “democracy and democratic traditions”.
