The Sunak government pursued the position of “assisting Ukraine to counter Russia” established during the Johnson’s premiership. The UK therefore continued to be the “vanguard” and “leader” in supporting Ukraine from July 2023 to June 2024 by repeatedly increasing and expanding its military assistance and training to Ukraine. The UK also formed air，maritime and drone “capability coalitions” aimed at sustainably arming Ukraine accordingly with a number of other countries. The UK was also the first country to sign a long-term bilateral security agreement with Ukraine. At the same time，the UK continued to strengthen and promote NATO’s influence in Europe actively. In terms of its policy towards Russia，the UK continued its war for opinions，expanded sanctions and continued to decouple from Russia in areas of energy，trade and commerce. The four main drivers for the UK’s adherence to these positions and policies are：being the ideological leader in Europe through the Ukraine crisis；strengthening its political and strategic influence on Europe；increasing its strategic weight on USA’s agenda；and satisfying a number of political demands within the country. The statements and a series of actions made by the Labour government after rising to power in July 2024 suggest that the Labour Party will not move away from the policies implemented by the Conservative government toward the crisis，and the UK will maintain its current stance.
