SDLP figures on board of Iona Institute
Two leading SDLP figures are among the board members of the recently-established northern arm of the socially conservative Iona Institute.
Mr O'Loan's wife, former police ombudsman Nuala O'Loan, is the Iona Institute's patron.
The other two board members are Brett Lockhart QC and fellow barrister Mary Lewis.
The Iona Institute established a northern operation last year as a "sister organisation" to its counterpart in the Republic.
Mr Maginness said it provided an "intelligent, intellectual resource for Christian thinking in Northern Ireland".
"While it's primarily Catholic it wouldn't be exclusively Catholic," he said.
In the wake of last month's Eighth Amendment referendum result, Sinn Féin leader Mary Lou McDonald said the group was "tone deaf to women".
