"Democracy was murdered in London, so it's more than a simple burial ceremony that we're taking part in today. This happens to be a murder trial. I enlist you all, as an Ulster jury - you have heard the evidence against Margaret Thatcher and her murder of democracy - how do you find her? Guilty or not guilty?" - Mr Robinson campaigning against the 1985 Anglo-Irish Agreement
"I am a patient man," when asked how he had coped with waiting so long to become leader of the Democratic Unionist Party (DUP).
"You will appreciate how devastated I have been about what you have learned from Iris. This has been the most difficult period of my life and I have been deeply hurt by what has happened.

"I was telling the consultants my eating arrangements of the last seven days before I was admitted to hospital. They included two Chinese meals, a Kentucky Fried Chicken, a McDonalds and a cowboy supper, plus the normal meals you get at business lunches and all the rest of it... the trouble is you are not at home to get regular, good, homemade food." Mr Robinson talking to the Belfast Telegraph after he was admitted to hospital with a heart attack in May 2015.
"I repeat, I neither received, expected to receive, sought, nor was I offered a single penny as a result of the Nama sale," Mr Robinson telling a Stormont committee in October 2015 that it was "outrageous" to allege he was to benefit personally from the sale by the Irish National Assets Management Agency (Nama) of its Northern Ireland property loan portfolio.

"There's no way I'm the kind of person who's going to sit and idle around the house and get in Iris' way. I'm going to be someone who finds something to do - I suspect it probably won't be politics, but we'll see as time goes on." The outgoing DUP leader on his plans for the future.
