NEW DELHI: Reflecting its current political dominance, Bharatiya Janata Party not only managed to get more political donations than other six national parties put together in 2015-16 but also increased its share, cornering over 55% of all funding compared to 51% in the previous year.Though the volume of donations to the national parties fell 41% from Rs 1,869 crore in 2014-15 to 1,033 crore, BJP and Congress mopped up over 80% of contributions with CPM being the only other national party with more than Rs 100 crore funding, data collated by Association for Democratic Reforms (ADR) shows.But as in the past, an analysis of income tax returns of the parties showed that “unknown sources” of income — where the source of donations under Rs 20,000 was not disclosed — accounted for a majority of contributions as BJP and Congress relied on coupon sales, relief fund and contributions from meetings and morchas.Of the 19% of the fund raising for BJP from known sources — where details of the donors have been disclosed to the Election Commission — donations of over Rs 20,000 added up to around Rs 77 crore (13% of the total income).In contrast, Congress earned over one-fifth of its income in 2015-16 (Rs 55 crore) through sale of assets, membership fee, interest on bank deposits and sale of publications.A little over Rs 20 crore, which was less than 8% of its total income, was from donations of over Rs 20,000, where names have been disclosed.Interest income is one aspect where Congress beats the BJP on the income front, having earned close to Rs 45 crore during 2015-16, compared to a little under Rs 20 crore for BJP.Cleaning up political funding has been identified as a key thrust area by the BJP government, which has decided to ban funding of over Rs 2,000 in cash. Besides, bonds are also to be introduced to protect the identity of the donors, which the government argued results in cash donations. Interestingly, only around three-fourths of the income earned by the seven political parties was spent.
