Campaigners against the use of cluster bombs declared the historic announcement in Dublin a triumph.

Simon Conway, co-chair of Cluster Munitions Coalition, said: "It's a combination of years of work and we are extremely happy.

"We think this will make a huge difference to people around the world and it will save many lives and limbs."

Mr Conway said the Irish Government produced a draft treaty text and the states came together and pushed it through without any changes.

He also paid tribute to British Prime Minister Gordon Brown, who declared that the UK would scrap all its cluster bombs.

"We got a very strong treaty," said Mr Conway.

"It's very strong on victim assistance, it's very strong on obligations to clear contaminated land and it's a very strong prohibition that we're extremely happy with."

In a statement released by Downing Street, Mr Brown said: "I am delighted that the negotiations in Dublin have come to a successful conclusion, and congratulate the Irish Government and all those involved.

"I am confident that this agreement is in line with British interests and values, and makes the world a safer place."
