Investigation launched into data breach as 12-week virus “shielding” letters sent to wrong addresses

The Information Commissioner’s Office (ICO) has launched an investigation as up to 13,000 letters – asking the most at-risk groups to stay at home for 12-weeks during the coronavirus pandemic – were sent to the wrong addresses.

The mistake has since been rectified and the Welsh Government blamed a data processing error by the NHS Wales Informatics Service.

Opposition AMs called the breach “potentially disastrous” and “unacceptable”.

The ICO said: “People have a right to expect their personal information to be protected. We’ll bear in mind the current crisis when assessing breach reports such as this, taking an appropriately proportionate approach.”
