It is necessary to clear up Shapps's comments after some misreporting. He stated that British training of Ukrainian troops may take place in the country further down the line but, for the time being, it's not being considered. There are no plans to have UK forces fighting in Ukraine.
While the training itself may not yet be taking place in Ukraine, the UK is already deeply involved in supporting the Ukrainian war effort — including through weaponry, intelligence, and even the provision of British troops on the ground. The UK's heavy involvement in the conflict is bringing the country dangerously close to a direct confrontation with Russia.
