Material uncertainty over going concern
Material uncertainty related to going concern: We draw attention to note 2.4 in the financial statements, which indicates that the Group and Company will require additional funding in order to meet its liabilities as they fall due over the period of at least 12 months from the date of approval of these financial statements. As stated in note 2.4, these events or conditions indicate that a material uncertainty exists that may cast significant doubt on the group's and the parent company's ability to continue as a going concern. Our opinion is not modified in respect of this matter.

Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers
