Volodymyr Zelenskiy made a powerful appeal to the UK to supply Ukraine with fighter jets in a historic speech to members of the Commons and the Lords at Westminster Hall. He presented Lindsay Hoyle, the speaker of the Commons, with the helmet of a fighter pilot on which the pilot had written: “We have freedom. Give us the wings to protect it.” Zelenskiy’s appeal may be broader – an effort to persuade the UK to act as a lobbyist to help Ukraine secure F-16s from the US, with Britain helping, as announced, with initial pilot training in simulators to get the process going.
