Assuming it will be confirmed that the Electoral Commission has found irregularities in the spending return filed by the official leave campaign for the EU referendum (Report, 5 July) and that this campaign failed to comply with electoral law, further doubts will inevitably arise as to the legitimacy of the result. The Venice commission, which advises the the Council of Europe on constitutional matters, has ruled that campaigning overspend is grounds for annulling an election result.
We have no domestic remedy for this approach in UK law but, given the evidence of breaches of electoral law by both the main leave campaigns, the mandate for Brexit is seriously undermined. In these circumstances, as MEPs with the best interests of our country at heart, we consider that this situation enhances the case for a people’s vote on the actual Brexit deal to ensure that any final decision to leave the EU is based on an unchallengeable mandate.
