As many as 170 MLAs deserted the Congress during the elections held between 2016 and 2020, while only 18 BJP legislators switched parties to contest the polls, it said. Five Lok Sabha MPs quit the BJP to join other parties during the 2019 Lok Sabha polls while seven Rajya Sabha MPs left the Congress to contest elections on another party's ticket in the same period.
"It is to be noted that the recent fall of governments in Madhya Pradesh, Manipur, Goa, Arunachal Pradesh and Karnataka State Assemblies were due to defections of their MLAs," the report said.
Ten of the 16 re-contesting Rajya Sabha MPs who switched political parties joined the BJP and five of the 12 Lok Sabha MPs who changed parties joined the Congress during the 2019 parliamentary polls.
