TaxationTaxation for the year comprises current and deferred tax. Tax is recognised in the Income Statement, except to the extent that it relates to items recognised in other comprehensive income or directly in equity.Current or deferred taxation assets and liabilities are not discounted.Current tax is recognised at the amount of tax payable using the tax rates and laws that that have been enacted or substantively enacted by the statement of financial position date.Deferred taxDeferred tax is recognised in respect of all timing differences that have originated but not reversed at the statement of financial position date.Timing differences arise from the inclusion of income and expenses in tax assessments in periods different from those in which they are recognised in financial statements. Deferred tax is measured using tax rates and laws that have been enacted or substantively enacted by the year end and that are expected to apply to the reversal of the timing difference.Unrelieved tax losses and other deferred tax assets are recognised only to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits.Foreign currenciesAssets and liabilities in foreign currencies are translated into sterling at the rates of exchange ruling at the statement of financial position date.
