Question to the Home Office:

To ask His Majesty's Government whether they have made an assessment of the annual revenue earned in the UK by global technology platforms from fraudulent advertising.

The information requested is not currently available from published statistics.

Under the Online Safety Act, the largest social media and search services will soon be required to address fraudulent adverts on their platforms. Ofcom are due to consult on these duties next year.

Companies in the sector are also working with the government through the Online Advertising Taskforce, to enhance voluntarily initiatives to tackle the drivers of illegal advertising.
