Northern Ireland's Deputy First Minister says he has not ruled out meeting the Queen in the future.
Speaking to the BBC, Sinn Fein's Martin McGuinness said he was still pondering the issue and that the royal visit to the Republic last May, made an impact on him.
During the Queen's first visit to the Republic of Ireland last summer, Sinn Fein didn't take part in any of the main ceremonies.
However, when he launched his presidential campaign last year, Mr McGuinness said he would be prepared to meet all heads of state "without exception", if he was elected President of Ireland.
After placing third in the first preference vote in the election, he returned to the role of deputy First Minister of Northern Ireland.
