A spokesperson for the BBC said: "Today's Talkback programme was a wide-ranging discussion on the political career of Gerry Adams on his final day as President of Sinn Fein".
Adams, who announced in November he was stepping down after nearly 35 years, was the key figure in the peace process that saw the signing of the 1998 Good Friday Agreement and the formation of a power-sharing government between Northern Ireland's pro-British and republican factions.
We have a Good Friday Agreement.
"They need to embrace the need for rights for everybody and agree a space where we can all moderate our differences".
Mr. Adams's retirement after 34 years as party leader is seen as an opportunity for Sinn Fein, until recently the political wing of the banned Provisional Irish Republic Army, to reposition itself closer to the political mainstream in southern Ireland.
McDonald immediately put her own stamp on the future, trying to infuse new energy into the movement that has lawmakers on both sides of the Irish border.
'Our focus must be on building Sinn Fein into an organisation that is fit for objective, and our goal is to win, to win elections, to increase our political strength, to realise our ambition of being in government north and south, to win progressive political victories every single day. "I regret that it took so long", he said. Northern Ireland has been without a government since January 2017 and the two main parties are still unable to reach an accord.
Before his entrance on the show, however, Garth Brook' If Tomorrow Never Comes played to welcome him on to talk about his life and legacy now that he's retiring from the Sinn Féin party.
"We have made some progress but there are still considerable obstacles".
In a statement last night, Mr Adams said he believes that a way forward can be found to restore the power sharing executive at Stormont.
He said he had simply tried to do his best during his decades at the helm.
The British government, which is overseeing the talks with the Irish government, has taken steps towards ruling the region directly from London for the first time in a decade, setting its budget late a year ago.
In her speech Saturday, McDonald said with the party's new leadership, it was time to bring "innovative and modern ways of advancing our politics", reports The Guardian.
