The government is to introduce its long-awaited Online Safety Bill in Parliament on Thursday.
The bill is intended to tackle a wide range of harmful online content, such as cyber-bullying, pornography and material promoting self-harm.
Social networks could be fined or blocked if they fail to remove harmful content, and their bosses could be imprisoned for a lack of compliance.
Labour said the bill's delays meant disinformation in the UK was growing.
