Taoiseach appoints second 'Brexit secretary'
Taoiseach Enda Kenny has appointed a second Secretary General in his department to deal specifically with challenges associated with Brexit.
John Callinan, who served as Head of the Economic and International Policy Division at the Department of the Taoiseach since 2011, has formally taken up the new post.
He will now lead a new integrated division within the department.
He will have specific responsibility for supporting the Taoiseach in his work on European Union, Northern Ireland, British-Irish and international affairs.
"The appointment is part of a series of actions announced by the Taoiseach following the recent Brexit referendum," a Government spokesman said.
"This includes the strengthening of the EU policy role of the Department of Foreign Affairs and Trade as well as the strengthening of other key departments, agencies and overseas missions."
Mr Callinan was responsible for Northern Ireland policy and British-Irish relations from 2011 to 2015.
Prior to that, he served as Head of the EU Division in the Department of the Taoiseach for four years from 2007 to 2011.
He has also worked in the European Commission and in the Revenue Commissioners.
During his time as Head of the Economic and International Policy Division, he worked on Ireland's exit from the Troika programme and in the implementation of the Action Plan for Jobs.
