In July 2014, Mark d'Arcy of the BBC named Baron his choice in "Parliamentarians of the Year" for 2013/14 for his role in opposing military action in Syria and seeking a promise of a referendum on membership of the European Union, writing that "he is not a household name or a fiery orator, but his fingerprints are all over the two most significant parliamentary events of the last 12 months." He voted against further airstrikes in 2015.
