Prime Minister John Major went to Northern Ireland and Scotland Monday to stress his commitment to the United Kingdom, an issue he has emphasized in the waning days of the election campaign.

Major's trip, with a later stop in Wales, underlined his opposition to the Labor Party's plans to give some legislative responsibilities to assemblies in Wales and Scotland."The U.K. has four components. The interest of the government extends to every part of the U.K.," Major said in Belfast.

Labor leader Tony Blair, meanwhile, attacked the Conservatives Monday and warned supporters against being overconfident as the May 1 election nears.

"I think there is something slightly absurd about Mr. Major touring round the U.K. saying that Scottish devolution is a disaster for the U.K. when what he proposes for Northern Ireland is precisely (the) same," Blair said.

Britain and Ireland jointly have proposed a form of self-government for Northern Ireland, but have said they will support any agreement reached in all-party negotiations.

Labor has supported the government's policy and Northern Ireland has not been a campaign issue.

A Gallup Poll published Monday showed Labor 19 points ahead of the Conservatives. The margin of error is about plus or minus 3 percentage points.

"The only poll that counts is on election day," said Blair.

At his morning news conference, Blair focused on the government's program of introducing market system economics into the National Health Service. He also pledged that a Labor government would "the scandal of patients waiting for hours on trolleys in hospital corridors."
