Gay sex is unnatural and the BJP cannot justify it, party president Rajnath Singh has said, finally making his party's stand clear on the Supreme Court's December 11 order in favour of Section 377 of the Indian Penal Code that criminalises homosexuality.

"Gay sex is not natural and we cannot support something which is unnatural," he told a newspaper on Saturday.

To another newspaper, he said: "We usually honour Supreme Court judgments.How can anyone justify unnatural acts?"

Later, BJP spokesperson Mukhtar Abbas Naqvi told a news channel that Rajnath Singh's remarks on section 377 were "correct".

He said it was not right to bring Western culture into Indian society and its culture.

Earlier, BJP MP Yogi Adityanath too reportedly said he would oppose any move by the Congress-led central government to amend Section 377. he said he would oppose any move to decriminalise homosexuality.

However, senior BJP leader Sushma Swaraj had said the party did not comment of Supreme Court orders and asked for an all-party meet to discuss any proposed amendment to Section 377.

BJP's prime ministerial candidate Narendra Modi, however, has refrained from commenting on the controversial topic.

Congress party chief Sonia Gandhi has called the Supreme Court verdict "disappointing" and urged p[parliament to uphold gay rights by deleting or amending Section 377 of the Indian Penal Code.

The Supreme Court has held that consensual sex between adults of the same gender is a criminal offence, leaving the lesbian, gay, bisexual and transgender community dejected.

Setting aside a Delhi High Court verdict of 2009 that decriminalised sexual relations between people of the same sex, Justice G.S. Singhvi and Justice S.J. Mukhopadhayay said there was no constitutional room for a change in Section 377 of the Indian Penal Code.

The section holds that same-gender sexual relationship is against the order of nature and an offence entailing imprisonment up to life sentence.

The court upheld the constitutional validity of section 377. But it said the government was free to amend the law.
