Not initially clear if any data has been stolen or if the party was the intended target
Labour has revealed it has been hit by a “cyber incident” meaning that a “significant quantity” of data provided by members and supporters had become inaccessible.
The party said the impact of the incident, affecting an external supplier, was not yet clear, but said that it was urgently investigating in an email sent to members shortly after lunch. Police, cybersecurity specialists and regulators had been notified, it added.
