What responsibility do corporates have to promote LGBTQ rights in countries where homosexuality is still illegal, or gay people are widely persecuted?

Ed Butler speaks to Mark McLane, the global head of diversity and inclusion at Barclays, one of the sponsor's of London's pride march this week about what his company is doing in the many countries in which it operates, including the US, where legislation still limits LGBTQ rights. And Nigerian actor Bisi Alimi tells his personal story of why he had to flee his home country because of his sexuality, and why he is now lobbying multinational firms to do more to protect gay and lesbian staff in Nigeria.
