Deferred tax is recognised in respect of all timing differences that have originated but not reversed at the balance
sheet 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 period 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.
