Protesters gathered in Bristol to petition the Government for arms trade control yesterday.

Campaigners wore t-shirts with bullet holes and giant sunglasses with the slogan "we are watching" as they handed a giant letter to a Bristol MP.

The protest marked the end of this week's international Control Arms campaign. Protesters petitioned for the formulation of an international arms trade treaty to move forward – 153 governments voted for one at the UN two years ago.

More than 800 society groups from 120 countries took part in the campaign.

In Bristol, Kingswood MP Roger Berry joined Oxfam campaigners in Castle Park to raise awareness.

"David Milliband has spoken in favour of a strong treaty and the UK government will continue to press for the political will needed to make this happen, and to persuade those opposed to an Arms Trade Treaty that it must go forward," he said.

Hannah Durrant, a Bristol Oxfam campaigner, said: "Now we have our last chance to push governments around the world as hard as we can in an attempt to save as many as a thousand people's lives every day."

"Bristol has always been a very strong supporter of the treaty and we hope support will continue."
