- "He has gone Glenn–tal"

Glenn Cullen, is a former special adviser to Fergus Williams, the junior minister in the Department of Social Affairs and Citizenship. He previously worked as a senior special advisor to Hugh Abbot and Nicola Murray.
When he was younger, both his appendix burst and his mother died on Christmas Eve.
Divorced, he has one son, Peter, who has special needs, with his ex-wife. He also has a sister, who lives in Penarth, South Wales, whom he routinely helps with DIY work.
Long time friends with Hugh Abbot, he worked as his senior special adviser prior to the events of Series 1. He continues in this capacity after Hugh is promoted to the Secretary of State for the Department of Social Affairs and Citizenship.
He is introduced as Hugh Abbot's chief adviser and friend and later became Senior Adviser to Hugh's replacement Nicola Murray, he continued to work in DoSAC after the coalition government came to power.
Glenn is the Senior Special Adviser in the department - he's never worked anywhere else. Hugh Abbot regarded him as 'his guy' they go back a long way and were even slightly homoerotic in the degree to which their careers and lives were bound together. However Hugh is gone now how will Glenn cope with new minister Nicola Murray.
Glenn very much senses that the whole department is living on borrowed time and thus is quite insecure.
This saw the end of Glenn's career, after he accidentally leaked some files about the jokes his colleagues created about the unstable nurse Douglas Tickel, this lead to an enquiry and whilst Glenn hadn't been found out, he was paranoid that he would be sniffed out eventually, so he had a big rant, insulting everyone in the department, cut up his ID card he used to get into the building, and decided to hand himself over to the police, but changed his mind at the last moment.
