Students at King’s College London have accused Lord Carey of being homophobic and are campaigning to have his photo removed from the college’s display of famous alumni.

The former Archbishop of Canterbury graduated from the college in 1962 with a 2:1 Bachelor of Divinity (BD) degree and was subsequently ordained.

According to the London Evening Standard, King’s College Student Union have described his recent comments against equal marriage as “outdated, hurtful and offensive”.

He was roundly criticised by equality campaigners in October after invoking memories of the Holocaust during a speech concerning the religious opponents of the measure at a Tory conference fringe event.

Lord Carey said: “Same-sex relationships are not the same as heterosexual relationships and should not be put on the same level. Why does it feel to us that our cultural homeland and identity is being plundered?”

He also warned that equal marriage would pave the way for traditional Mormon-style polygamous relationships, pointing to an application in Sao Paulo, Brazil, for a man to enter into a civil union with two women.

“That is getting into a Mormon-style relationship,” Lord Carey said after the event. “It’s a slippery slope.”

Meanwhile, Peter Tatchell has criticised King’s College London for continuing to display Lord Carey’s photograph.

“For more than two decades, Dr Carey has opposed gay equality and supported legal discrimination against gay people, suggesting that same-sex love is inferior and a scandal,” Mr Tatchell said.

“If Dr Carey said these things about black or Jewish people his display would almost certainly be removed. The stance of the King’s College administration looks hypocritical. They seem to have double standards on racism and homophobia.”

The university has said it has no intention of removing Lord Carey’s image.
