The BJP has declared a total income of Rs 1,027.34 crore during financial year 2017-18 and spent 74 percent (Rs 758.47 crore) of it, according to a report by the Association for Democratic Reforms (ADR).
The ADR said the Congress was yet to file its audit report for the year.
The BSP's total income during year 2017-18 was Rs 51.7 crore of which the party spent only 29 per cent (Rs 14.78 crore), the report said.
During 2017-18, out of the six national parties, only the BJP declared receiving an income of Rs 210 crore from contribution through electoral bonds.
The Communist Party of India (Marxists) alleged that the electoral bonds have become new 'tax havens' as commissions to be given to political parties are now being paid through these instruments and this was the case in the Rafale deal.
Yechury alleged it was clear that the BJP and the Modi government were facilitating crony capitalism and corporate funding for electoral benefit. The electoral bonds can be encashed by an eligible political party only through a bank account.
Only the political parties registered under Section 29A of the Representation of the People Act, 1951 (43 of 1951) and which secured not less than one per cent of the votes polled in the last General Election to the House of the People or the Legislative Assembly of the State, are eligible to receive the electoral bonds.
Trinamool Congress, CPM and BSP submitted their audit reports on time, while the CPI submitted after one day, NCP submitted after 20 days and BJP, 24 days after the due date for submission.
