Joe Biden has arrived in Britain tonight for talks with Rishi Sunak amid a growing row over cluster bombs for Ukraine.
The US President will send the controversial weapons to Kyiv to boost its fight against Russian invaders - opening a divide with the UK. Many NATO allies, including Britain, ban their use.
The Prime Minister said: “The UK is signatory to a convention which prohibits the production or use of cluster munitions and discourages their use.”
