The death has taken place of former Attorney General Rory Brady SC.
Mr Brady served as Attorney General from June 2002 to June 2007.

'As Attorney General, Rory Brady made a strong contribution to the Government in which he served,' Mr Cowen said.
Former Taoiseach Bertie Ahern said Mr Brady 'was a great Dubliner who had a strong affinity with his native city.
Mr Ahern added: 'He was a proud Irishman who has given this nation immense service.
'He was my closest and most trusted colleague at the cabinet table. He was never anything less than brilliant. It was a true privilege to work alongside such a dedicated and capable person.'
Mr Brady is survived by his wife and two daughters.
