LONDON (Reuters) - The chances of Northern Ireland s political parties restoring a power-sharing agreement in Northern Ireland are  not positive  and talks in the last few days have stalled, Britain s minister for the region said on Wednesday.  If I had given evidence to this committee last week I might have indicated some momentum, more progress. That progress stalled at the end of last week,  James Brokenshire told a parliamentary committee.  Unless there is a renewed spirit of compromise then the outlook for imminent resolution is not positive. Time is running out.
