President Michael D Higgins has said that Britain's Queen Elizabeth's state visit to Ireland should be returned by an Irish State visit to Britain early next year.

President Higgins is currently making his second official visit to London.

The President was visiting the west London headquarters of the GAA in London.

He attended the opening of a Druid production of three plays by Tom Murphy telling the story of Irish emigration at London's Hampstead Theatre.

The DruidMurphy series of plays is part of the London 2012 Cultural Festival, which is running in conjunction with the Olympic Games.

Earlier, President Higgins welcomed Sinn Féin's decision that Martin McGuinness should meet Britain’s Queen Elizabeth when she visits Belfast next week.

He said that the move would be very helpful in deepening relationships and reconciliation between communities in Northern Ireland.

He said it would be of positive value and assistance and that the Good Friday Agreement was not a finished project but a process of deepening and encouraging relationships.

Elsewhere, over 100 people have taken part in a Republican demonstration in Belfast in advance of the British Queen's jubilee visit.

The march was organised by the Truth and Justice - No Jubilation committee. 

Among those supporting today's event were relatives of those killed in Ballymurphy in West Belfast in the 1970s.
