The Data Protection Commission has rejected criticisms of its operation made by the Facebook whistleblower Frances Haugen.

Ms Haugen is due to testify before the Joint Oireachtas Committee on Tourism, Culture, Arts, Sport and Media tomorrow and is expected to call for an independent review of the Data Protection Commission.

Ms Haugen is expected to tell TDs and Senators that tech companies based in Ireland have "got away with it" when it comes to enforcing data protection regulations and that the Government should learn from these criticisms when establishing a new online safety regime.

Speaking to RTÉ's This Week programme ahead of her appearance, Ms Haugen said the world was depending on Ireland to enforce regulations like GDPR (General Data Protection Regulation).

"Ireland so far has not demonstrated that they are willing to live up to the letter of these laws," she said.

The Data Protection Commission has defended its record and has invited Ms Haugen to meet with them to discuss their work.

"We note the comments from Ms. Haugen on RTE's 'This Week' programme on Sunday last, where she was honest and forthcoming about her lack of knowledge of any specific investigations dealt with by the DPC and how agencies work in Europe," said Graham Doyle, Deputy Commissioner at the Data Protection Commission.

"Ms Haugen stated that comments about Ireland’s willingness to step-up stems from 'reading articles' and 'googling' news stories about the DPC," he added.

Mr Doyle said that the Commission will be publishing its annual report this week which will detail the extent of its work including the second largest fine delivered across the EU under the GDPR.

Frances Haugen left her job at Facebook last year claiming the company was guilty of harming children, stoking division and weakening democracies.

She also accused the social media giant of putting profit ahead of public safety.

Facebook's parent company Meta has denied the accusations.

"Contrary to claims about our company, we’ve always had the commercial incentive to remove harmful content from our platform," a Meta spokesperson said.

"While we have rules against harmful content and publish regular transparency reports, we don’t believe that businesses such as ours should be making these decisions on our own. We’re pleased that Ireland is progressing with the appointment of an Online Safety Commissioner, " the spokesperson added.
