Amritsar: Punjab Deputy Chief Minister Sukhbir Singh Badal on Sunday alleged that the Aam Aadmi Party (AAP) has "very close links" with radical organisations and also termed the recent incident of party MP Bhagwant Mann uploading Parliament's security set up on social media as a "very serious lapse". "I think it is a very serious (security) lapse, what Bhagwant Mann has done. I openly say that AAP has very close links with radical organisations," Sukhbir Singh Badal, who is also Punjab's Home Minister, told media after offering prayers at the Golden Temple, here on Sunday along with his wife and Union Minister Harsimrat Kaur Badal. Mann on Thursday shot a video clip of his journey from home to Parliament House, including movement past various security check points, and posted it on social media, drawing flak from various quarters for putting Parliament complex security in danger. Cornered by leaders of almost all parties in both the Houses, Mann apologised to Lok Sabha Speaker, Sumitra Mahajan and also removed the video from Facebook. "Radical organisation, people who participated in the 'Sarbat Khalsa' (grand assembly of Sikhs), they are all linked to AAP," Sukhbir said. Last November, radical Sikh organisations and others held the congregation of radicals near Amritsar.
