Mai i te 2012 ki te 2014, ko Darling te tumuaki o te Better Together Campaign, he roopu whakawhiti-rōpū i angitu te pakanga mo Scotland kia noho tonu hei waahanga o te United Kingdom i te pooti pooti motuhake o te 2014
He aha? I te 3 o Whiringa-a-rangi 2014, i kii a Darling kei te tu ia i te pooti nui 2015. I whakaingoatia ia mo te rangatiratanga o te ao i roto i nga Whakahonoretanga Whakakorenga 2015 a i hangaia ia hei Baron Darling o Roulanish, o Great Bernera i te Kaunihera o Ross me Cromarty, i te 1 o Tihema 2015. I reti ia mai i te Whare o nga Rangatira i te Hurae 2020.
