Swamy said there was nothing unparliamentary about the phrase 'mota maal' which was used by Swaraj while alleging that the Congress party received bribes in the allocation.
"These two words convey very graphically what in English will be called as a bribe. Therefore, the catchy phrase is easy to understand for the masses of India," Swamy said in a statement.
Congress chief Sonia Gandhi and Finance Minister P Chidambaram had taken objection to the use of the phrase by Swaraj at a press conference on Monday.
