Labour Party Data Breach Claim

The Labour Party has experienced a data breach.
Keller Lenkner UK can help victims to claim compensation for this data protection failure.

Have you been affected by the Labour party data breach?

The Labour Party has experienced a data security incident involving “a significant quantity of party data”. While the full details are not yet known, the incident has rendered the data “inaccessible”. This often happens after ransomware attacks.

The Labour party has written to those affected – including Party members – and advised them to take steps to protect themselves.

The data privacy failure occurred when a third party that handles data on behalf of the Labour Party was subject to a cyber incident.  The Labour Party was made aware of the incident on 29 October 2021 but took five days to inform those who could be affected. This delay could have left them vulnerable and exposed to cybercriminals.

Keller Lenkner UK is launching an action to help those involved in this data privacy failure. 


Why claim Labour Party data breach compensation?

Hold the guilty party to account for failing to protect your private information.

Receive financial compensation for your losses.

Force organisations to implement better data security.

Are you at risk following the Labour Party data breach?

Those affected by the breach have been informed. And they have been offered advice to manage any potential risks. This includes being vigilant against suspicious activity and implementing two-factor authentication (2FA) where possible. However, that people have been put in this position in the first place is a serious failure.

If you are concerned that your data might be involved, but you have not yet received a letter, you can check your spam folder and/or email privacy@labour.org.uk for further information.

We would warn people to be suspicious of any emails purporting to come from the Labour Party about this incident. Criminals often use the fear and distress caused by a breach to encourage people to click on phishing links and steal valuable personal information.

What can you claim for?

While each case is judged on its own merits, there are some things we would typically look for when it comes to when claiming compensation following a data breach, cybercrime or other GDPR violation:

Financial loses

With stolen data, cybercriminals can make purchases using your bank and credit cards, apply for credit in your name, set up fraudulent bank accounts and access your existing online accounts.


GDPR failures, cybercrime and data breaches can have a significant impact on you, both mentally and physically. They can cause or exacerbate anxiety, stress and other psychological conditions.

Loss of privacy

Your data has value, and organisations must be held to account if they fail to protect your right to data privacy or otherwise do not uphold your GDPR rights.

How to protect yourself following a data breach or cybercrime

  • Contact your bank or credit card provider immediately if your financial data has been exposed.
  • Check all bills and emails for goods or services you have not ordered.
  • Check your bank account for unfamiliar transactions.
  • Alert your bank or credit card provider immediately if there is any suspicious activity.
  • Monitor your credit score for any unexpected dips.
  • Call Credit, Experian and Equifax to ensure credit isn’t taken out in your name.
  • Never provide your PIN or full password to anyone (even someone claiming to be from your bank).
  • Never been pressured into moving money to another account for fraud reasons. A legitimate bank won’t ask you to do this.
  • Follow the security instructions provided by the organisation that breached your data.
  • Never automatically click on any suspicious links or downloads in emails or texts.
  • Don’t assume an email or phone call is authentic just because someone has your details.
  • Be careful who you trust – criminals often use scare tactics to try and trick you into revealing your security details.
  • Know that, even if you recognise a name or number, it might not be genuine.
  • Don’t be rushed or pressured into making a decision. A trustworthy organisation would never force you to make a financial transaction on the spot.
  • Never provide your full password, pin or security code to someone over the phone (or via message). If a bank believes a transaction has been fraudulent, they will not ask for this information to cancel the transaction.
  • Listen to your instincts and ask questions if something feels “off”.
  • Refuse requests for personal or financial information and stop discussions if you are at all unsure.
  • Contact your bank or financial service provider on a number you know and trust to check if a communication is genuine.
  • Be cautious of unsolicited communications that refer you to a web page asking for personal data.
  • Don’t accept friend requests from people you don’t know on social media.
  • Review your online privacy settings.
  • Report suspected fraud attempts to the police and Action Fraud.
  • Register with the Cifas protective registration service to slow down credit applications made in your name.
  • Change your passwords regularly and use a different password for every account (a password manager can help with this).
  • Protect your devices with up-to-date internet security software.
