Speaking at an event at Queen's University Belfast marking the 25th anniversary of the Good Friday Agreement, Irish Prime Minister Leo Varadkar "rededicates" his government's efforts to the peace process, calling for a renewal of political leadership in Northern Ireland's power-sharing executive as it remains shut down due to a boycott by the DUP over post-Brexit trading arrangements with the EU. Varadkar pledges to "work with all of the parties in Northern Ireland, and with our partners in London, to drive the process forward to the benefit of everyone on our islands." IMAGES AND SOUNDBITES
