There was one major party in Northern Ireland that did not participate in the multi-party talks that resulted in The Good Friday Agreement. The DUP, led at the time by Ian Paisley, refused to engage in the negotiations and campaigned for a 'No' vote in the referendum that followed. Peter Robinson, who took over as leader of the party and served as First Minister in the Northern Ireland Assembly from 2008 until 2016. explains to Bertie why the party stayed out of the talks, why he regrets not engaging with Sinn Féin sooner and what aspects of the agreement he thinks have been a success.
