Varun Gandhi, a BJP parliamentarian, has made a reference to his Nehru-Gandhi lineage at a rally in Sultanpur as he campaigned for mother Maneka Gandhi. Mr Gandhi attacked his mother's opponent Chandra Bhadra Singh alias Sonu Singh, a Samajwadi Party and Bahujan Samaj Party's joint candidate, saying he was Sanjay Gandhi's son and he made such people untie his shoelace.
