U.S. President Joe Biden begins his UK trip on July 9, amid opposition from the United Nations and U.S. allies to Washington's plan to deliver controversial cluster munitions to support Ukraine. Biden is expected to meet with UK Prime Minister Rishi Sunak, who has expressed concern over Washington's decision. Sunak says the UK is one of the 123 signatories to the Convention of Cluster Munitions, an international treaty which bans the production or use of the weapon. The Biden administration announced on July 7 to provide cluster munitions to Ukraine, as part of a new military aid package worth up to 800 million dollars.
