Martin Warne has the story about the Labour Party in West Ham:
Branch secretaries across West Ham Labour party have received an email today from Josephine Grahl, the vice chair for membership, about a serious data breach in Green Street West:
Dear Branch Secretary,
I am writing to draw your attention to a recent incident in which personal membership data of individuals may have been misused or accessed by an unauthorised person.
In September 2017, following the third attempt to hold a branch AGM in Green Street West, a number of members in that ward reported to the CLP Secretary and to myself that their Labour Party membership had been resigned without their knowledge ahead of the AGM. Emails were sent to the National Membership team purporting to be from these members, quoting their Labour Party membership numbers and home addresses, and stating that they wished immediately to resign their Labour Party membership.
Sensibly, the email goes on to explain, the Labour Party has been undoing these dodgy resignations, restoring people’s membership of the party.
As the email sent out adds:
This has been reported to both the police and the Information Commissioner alleging illegal misuse of personal data. The matter has also been referred to the Labour Party’s Governance and Legal Unit.
