In July, a report on British data law commissioned by Cameron advised UK intelligence services to retain powers to collect mass communications data, but deprive ministers of their powers to authorize surveillance.
"We’ll set out our plans on Wednesday, but politicians have a role – not least to get this area of law right," Cameron told the ITV channel in an interview, when asked about whether he agreed with the report.
The interview comes amid a UK government plan to publish on Wednesday a draft Investigatory Powers Bill on the operation and regulation of powers used by police, intelligence, and security agencies.
Cameron declared that the bill would keep UK citizens safe and stop terrorists and other criminals from communicating via the Internet without being traced.
The bill may introduce a two-stage approval process of surveillance warrants in which senior judges would be confirming the ministers’ initial order to monitor communications data, according to media reports.
