Stormont Deputy First Minister Martin McGuinness signed a book of condolence in Derry's Guildhall today for Ian Paisley.

The former Northern Ireland first minister, leader and founder of the DUP party died yesterday morning aged 88.

Mr McGuinness said the peace process and he himself had lost a friend.

He said "we have to rise above the old enmities", as he and Mr Paisley had done. 

A similar tribute to Mr Paisley is to be opened at Belfast City Hall on Monday.

Senior US figures including former President Bill Clinton and US Vice President Joe Biden have paid tribute to Mr Paisley.

In a statement late last night, Mr Clinton described the former Northern Ireland first minister as someone who was once a polarising figure.

He said he had showed that reconciliation and co-operation are better than conflict and discord.

Vice President Biden said the former Democratic Unionist Party leader demonstrated that someone with strong convictions could still seek meaningful compromise in search of a lasting peace.

A private family funeral will be held in the coming days with a public memorial service to take place later.  

Mr Paisley is survived by his wife Eileen, whom he married in 1956.

They have two sons - Ian Jnr holds his father's former Westminster seat, while Kyle is a minister in his father's church - and three daughters, Rhonda, Sharon and Cherith.
