An invitation to the president of Ghana to address MSPs undermines the safety of the Scottish parliament for members of the lesbian, gay, bisexual and transgender (LGBT) community, according to opposition MSPs.

The MSPs are joining with human rights campaigners to call on the Scottish government to confront President John Dramani Mahama about his country’s abuses of its lesbian and gay citizens.

Mahama received muted applause from the Holyrood chamber as he listened to FMQs on Thursday morning, but a meeting with opposition leaders was cancelled.

After the Scottish parliament’s presiding officer, Tricia Marwick, said she would “extend the hand of friendship” to Mahama, members of the Scottish Greens, including their co-convenor Patrick Harvie, who is gay, wrote to her on Wednesday to urge caution.

They said: “We believe that the Scottish parliament should be a place where everyone can feel safe. Yet the invitation to President John Dramani Mahama to address MSPs can only undermine this, given his full support for the horrific discriminatory laws towards the LGBT community in his country.”

Ghana is one of 75 countries around the world where it is still illegal to be gay, carrying a sentence of up to three years in prison.

While the director of Stonewall Scotland, Colin Macfarlane, acknowledged “some promising statements from President Mahama criticising violence against LGBT communities”, he went on to call for the Scottish government to recognise its “important responsibility to help advance the protection of LGBT rights across the world”.

Responding to calls from opposition leaders, a Scottish government spokesperson confirmed that the first minister would “share her strong view that the Commonwealth values of humanity, equality and tolerance are universal values” during the president’s visit.

Naomi McAuliffe, Amnesty International’s programme director in Scotland, said her organisation received regular reports that LGBT people faced police harassment, while repressive attitudes towards LGBT Ghanaians meant they were vulnerable to discrimination and physical attacks. This was against a background of the use of torture and ill-treatment by police and intelligence services, alongside widespread violence against women and girls.

McAuliffe said: “We understand opposition leaders and MSPs choosing not to meet President Mahama during his visit to the Scottish parliament as Ghana’s human rights record has serious failings. However, we are not calling for a boycott of the visit as we view this as an opportunity to raise our concerns about LGBTI discrimination, violence against women and girls, and the use of torture. Nicola Sturgeon’s commitment to raising ‘values of humanity, equality and tolerance’ is welcome and we look forward to hearing about any positive interventions.”

Mahama’s visit to Scotland will also entail him receiving an honorary degree from the University of Aberdeen on Friday. –
