Corporation tax was calculated at 19 per cent (2021: 19 per cent) of the estimated taxable result for the year.

On 4 March 2021, the UK government announced an intention to increase the rate of corporation tax to 25 percent with effect from 1 April 2023. During the year, this change has been confirmed and hence all deferred tax balances have been calculated at 25 per cent.
