The editor of the Guardian is to give evidence to MPs over documents leaked by whistleblower Edward Snowden.
A spokesman for the newspaper told Sky News that Alan Rusbridger had been "invited to give evidence to the home affairs select committee and looks forward to appearing next month".
It follows a series of articles published by the Guardian about the surveillance of phone and internet communications by the security services.
The revelations in the newspaper - and others around the world - were made in top-secret documents obtained by Mr Snowden, a former CIA computer analyst who has since fled to Russia.
Three of Britain's spy chiefs warned of the impact of the revelations On Thursday, three of Britain's spy chiefs warned that terrorists would be "rubbing their hands with glee" at the level of information released.
Al Qaeda would be "lapping up" the revelations, they told an intelligence and security committee hearing.
It also emerged that dozens of Conservative MPs had written to Mr Rusbridger, asking him to consult the Government or security services before publishing any further stories based on Mr Snowden's files.
In their letter, the MPs said that publishing the leaked information in such detail "runs the risk of compromising the vital work of the institutions, processes and people who protect the safety of this country".
The Guardian has published a series of stories based on Mr Snowden's leaks However, Mr Rusbridger said: "We continue to consult with both the security services and the Government on our reporting.
"We have in fact consulted with the White House, Downing Street (and) the intelligence services on both sides of the Atlantic ... on every story but one that we have published."
He added: "Snowden handed these documents to newspapers, who have responsibly edited them after prolonged and regular discussions with the relevant authorities.
"Were newspapers to be injuncted, criminalised or inhibited from reporting on such matters ... it is easy to predict what the next Edward Snowden or (fellow whistleblower) Chelsea Manning would do.
"They would, in all probability, bypass newspapers and publish the material directly on to the web, with far more serious consequences."
