In this episode Sarah talks to the uncompromising campaigner Peter Tatchell, who has just marked his 50th anniversary of being in the front line of tackling human rights abuses and challenging the status quo in the interests of equality. He's been prominent in British public life, fighting for LGBT rights and is well known around the world for his unflinching position in defending LGBT people. He also supports indigenous groups of people suffering unfairness in marginalised territories. Peter has been known to put his own health and safety at risk to further these cases. Listen to what inspires him to act, the lessons learned on his campaigning journey and how it has taken him from speaking out for the rights of people to becoming a voice for the planet. As he says, 'The price of freedom is eternal vigilance'
