In a statement, Singh alleged that Sukhbir was insulting the entire Sikh community by branding everyone opposed to him as "terrorists".
The senior AAP leader said in 2011, he had given an eight-minute speech at the Remembrance Day meeting, which is held every year at Trafalgar Square in London, in which he had strongly flayed the role of Congress leaders Sajjan Kumar and Jagdish Tytler in the 1984 riots.
Singh said he had worked for the welfare of the victims of the 1984 anti-Sikh riots who, he alleged, were denied justice by respective Congress and BJP-led governments at the Centre.
He wondered if he had any link with radicals, why had the Shiromani Gurdwara Parbandhak Committee (SGPC) honoured him with 'siropa' for serving the Sikh community and helping the victims of the 1984 riots.
He alleged that the Badal family had always looked after their own interests and made Punjab a "mandi (market) of drugs and sanctuary of criminals and mafias".
