Union Flag Flying Over Belfast City Hall To Mark Kate Middleton's 31st Birthday

The Union flag was flying over Belfast City Hall on Wednesday morning to mark the Duchess of Cambridge's 31st birthday, for the first time since the controversial decision to only raise it on designated days.

A special meeting of unionist representatives in Northern Ireland has been called in a bid to end loyalist unrest the decision sparked.

Loyalists pelted police with bottles and stones in a new outbreak of trouble in east Belfast last night amid warnings that potential investors are turning away because of the street violence.

With riot police again facing hundreds of masked men around the lower Newtownards Road area, there is no sign of a halt to the protests.

Fireworks, rocks, golf balls and petrol bombs were fired at police lines on the sixth consecutive night of violence in the confined flashpoint area of east Belfast.

Northern Ireland First Minister Peter Robinson confirmed that representatives of the various unionist parties will meet at Stormont tomorrow to discuss the trouble, but leaders centrally involved in the protests who are threatening to take their campaign on to the streets of Dublin on Saturday have pledged they want no part in the discussions.

The Confederation of British Industry (CBI) claimed jobs would be lost and shops shut unless there is an immediate end to the trouble.

CBI Northern Ireland director Nigel Smyth warned: "We are already aware of investors who have lost interest because of these disruptions."

The unrest has continued intermittently since Belfast City Council's decision last month to reduce the number of days the flag flies to 18 days. A total of 66 officers have been hurt and 104 arrests made since the protests started a month ago.

Businesses, especially restaurant owners, said the disruption has had a disastrous impact on trade.

On Monday night, in a fierce debate over raising the flag at the height of the tensions, opposing politicians accused each other of political game-playing over the birthday flag-raising.

Democratic Unionist councillor for east Belfast Robin Newton accused McVeigh and Sinn Fein of "bulldozing" the flag vote through council.

"It was purely a political decision, a pure political decision," he said, rejecting the claims that unionists had not shown leadership.
