13. Deferred tax

At present, the Company does not recognise deferred tax assets because their future recoverability is uncertain due to the extent of forecast tax losses available for surrender within the UK tax group to which the Company belongs. Deferred tax assets will be recognised when it is considered more likely than not that they will be recovered.
