Britain’s foreign minister James Cleverly on Tuesday said Russian President Vladimir Putin’s sequence of strategic errors must stop and that any use of nuclear weapons would lead to consequences. Reuters reports that Putin has escalated its seven-month war in Ukraine with a military mobilisation and warnings of nuclear weapons use. Asked how Britain would respond to the use of tactical nuclear weapons by Russia, Cleverly told a fringe event at the Conservative Party conference that he couldn’t go into detail but there would be a response.
