Mr Gandhi's remarks triggered a political slugfest.
Congress president Mallikarjun Kharge on Wednesday said there is no question of an apology over Rahul Gandhi's remarks in the UK and that those demanding so must answer on Prime Minister Narendra Modi "humiliating" the people of the country with his comments abroad.
The BJP and several senior ministers have been demanding an apology from Mr Gandhi over his "democracy under attack" remarks in the UK.
"I would like to ask a question to the people demanding an apology (from Rahul Gandhi) that (what about) when Modi ji went to five-six countries and humiliated the people of our country and we were told by him that being born in India is a sin," Mr Kharge said.
"Democracy is diminishing here, freedom of expression and speech are being weakened, TV channels are being pressured and people speaking the truth are being jailed, so if this is not the process of ending democracy then what is?" the Congress president told reporters here.
So, there is no question of an apology, he added.
Mr Gandhi's remarks during his recent trip to the United Kingdom have rocked Parliament, with both Houses failing to transact any significant business on the first two days of the budget session's second half.
During his interactions in the UK, Mr Gandhi alleged that the structures of Indian democracy are under attack and there is a "full-scale assault" on the country's institutions. The former Congress president also told British parliamentarians in London that microphones are often "turned off" in the Lok Sabha when an opposition member raises important issues.
Mr Gandhi's remarks triggered a political slugfest, with the BJP accusing him of maligning India on foreign soil and seeking foreign interventions, and the Congress hitting back at the ruling party by citing instances of Prime Minister Modi raising internal politics abroad.
