The death of my friend and comrade Martin McGuinness has left a deep void. It is a huge blow to all of us who knew and loved him, especially his wife and family. Martin was an extraordinary human being. Funny, caring, a committed family man, a keen fisherman, an enthusiast for all kinds of sport from cricket to hurling. He loved Derry. The city - along with his wife, Bernie, his family and his mother, Peggy - moulded him into the complex, compassionate, warm, human being he was.
