How much is UK supporting Saudi Arabia in its war with Iran-backed Houthis?

The United Kingdom announced it would provide military support to Saudi Arabia in its war against the Iran-backed Houthi group. British Prime Minister Andy Burnham stated that London had accepted a Saudi request for air-to-air refueling of Saudi fighter jets. While the UK will not directly engage in the conflict, fighting has resumed after a UN ceasefire in 2022, with intensified clashes around the strategic port city of Mocha.
