Boris Johnson repeats warnings by ministers and chief of defence staff that joining resistance against Russian invasion is illegal
British soldiers who travel to Ukraine to fight can expect to be court-martialled, Boris Johnson has said, adding that civilians should also avoid going there to fight.
Asked about reports that a 19-year-old from Warrington with no military experience had travelled to the country to join efforts against the Russian invasion, the prime minister said that while he could comprehend why people wanted to help, they should remain in the UK.
