SNP deputy Westminster leader Mhairi Black has accused Kate Forbes of "intolerance" over her opposition to same-sex marriage.
Leadership hopeful Forbes has come under criticism after saying she "believes marriage is between a man and a woman". She also said she would have voted against gay marriage if she had been an MSP in 2014.
Black, who got married to her wife Katie last year, said that she had been "incredibly hurt" by Forbes' comments. She said that using religion to restrict the choice of others was "showing intolerance".
