A picture of former Archbishop of Canterbury Lord Carey at the Strand campus of King's College London (KCL) may fall victim to a campaign by gay activists.

And though he said he was "entirely relaxed" about the idea of the University changing the publicity on its building, he warned of the implied threat to free speech.

Lord Carey is a distinguished KCL alumnus, but has been targeted by the University's LGBT association for his views on gay marriage, of which he has been an outspoken opponent.

KCL's LGBT student council officer Ben Hunt told the university's Roar News: "The [university] principal has asked me to compile a list of new alumni for the window in suggestions.

"[This] will also mean the removal of Lord Carey and the inclusion of minorities in the discussions for new alumni."

A spokesperson for KCL said: "It is likely, subject to planning approval, that the proposed redevelopment of the Strand campus will require a review of the Strand windows and we will consider the diverse views of our students, staff and alumni at the appropriate time."

Lord Carey has been the target of KCL activists since 2012, when students described his statement at a Conservative party fringe event that "Same sex relationships are not the same as heterosexual relationships and should not be put on the same level" as "outdated, hurtful and offensive".

However, he said: "If this is indeed under discussion in the university, I am entirely relaxed about their approach to publicity on their building. I am a Fellow of King's College and that is more important to me than peering out of a wall onto the Strand.

"My greatest concern is what this says about the status of free speech in the universities especially in a period when it is under exceptional attack. I would imagine there is considerable diversity of views on same sex marriage among the alumni of King's, yet the great values of this institution, like other universities, is that different views are listened to, argued with and respected and the human rights of all are upheld, including those of the lesbian and gay community."
