The Taoiseach has discussed Northern Ireland with Prince Charles at their meeting in Government Buildings. The two men discussed improvements in community relations in the North, and Mr Ahern briefed the Prince about developments in the building up of relations between North and South.

At a ceremony at the British Ambassador's residence tonight, Prince Charles performed an investiture ceremony during which Daniel O'Donnell received his honorary MBE.

Earlier, about 40 people from Sinn Féin protested outside a drugs treatment centre on Merchant's Quay, which was visited by the Prince. He met staff and clients of the centre who have been affected by drug use and HIV, as well as homelessness.

Prince Charles attended a lunch at Áras an Uachtaráin hosted by President McAleese. The Prince also viewed a Californian redwood tree planted by his ancestor, Queen Victoria, in August 1861.

Prince Charles was greeted this morning on his arrival at Baldonnel by the Minister for Public Enterprise, Mary O'Rourke, on behalf of the Government.

The media asked him about the condition of his grandmother and he replied that she was in good form and that she was very resilient. He was also asked if the Queen was to visit Ireland. He said that he hoped so.

The Prince decided to go ahead with his trip despite the death of his aunt, Princess Margaret, last weekend.
