Nearly half of the newly-elected Lok Sabha members have criminal charges against them, a 26 per cent increase as compared to 2014, according to the Association of Democratic Reforms.
Of the 539 winning candidates analysed by the ADR, as many as 233 MPs or 43 per cent have criminal charges.
The BJP has 116 MPs or 39 per cent of its winning candidates with criminal cases, followed by 29 MPs (57 per cent) from the Congress, 13 (81 per cent) from the JDU, 10 (43 per cent) from the DMK and nine (41 per cent) from the TMC, the ADR said.
In 2014, 185 Lok Sabha members (34 per cent) had criminal charges and 112 MPs had serious criminal cases against them. In 2009, 162 (nearly 30 per cent) out of the 543 Lok Sabha MPs had criminal charges and 14 per cent had serious criminal charges, it said.
In the new Lok Sabha, nearly 29 per cent of the cases are related to rape, murder, attempt to murder or crime against women, the non-governmental organisation said.

Pragya Singh Thakur, the newly-elected BJP MP from Bhopal, faces terror charges in connection with the 2008 Malegaon blasts. The Bharatiya Janata Party has faced a lot of criticism for fielding her.
