Journalist Colm Keena (Irish Times) worked on the Panama Papers, as well as controversies concerning company and  personal tax avoidance and evasion. His story about payments to an  incumbent Irish Taoiseach in 2006, caused a political crisis and led to  landmark Supreme Court judgment in 2009 recognizing the right of  journalists to protect their sources.

Colm was interviewed by Belfast journalist Barry McCaffrey.
