(1)A tax credit has arisen in the year due to losses created in the period which have been carried back and offset against taxable profits arising in 2021.

(2)During the fourth quarter of the year ended 30 June 2021, the UK Corporation tax rate increase from 19% to 25%, effective April 2023, was substantively enacted, necessitating a remeasurement of the existing UK deferred tax liability position. This resulted in a non-cash deferred tax charge of £11,224,000 in the period. Furthermore, given the current US federal corporate income tax rate of 21%, we expect future US tax liabilities to be sheltered by future foreign tax credits arising from UK tax paid. Consequently, we have written down the existing US deferred tax asset, on the basis it is no longer expected to give rise to a future economic benefit. This has resulted in a further non-cash deferred tax charge of £66,561,000 in the year ended 30 June 2021. Future increases in the US federal corporate income tax rate could result in a reversal of the US deferred tax asset write down.
