The White House is set to call for major changes to the National Security Agency (NSA) phone metadata surveillance programme in the face of criticism of the US government for breaching citizens' privacy.

President Barack Obama is to present to Congress a proposal to scale back one of the most controversial US surveillance programmes.
The proposal is based on recommendations of the President’s Review Group on Intelligence and Communications Technologies, which delivered its report in December 2013.
Classified documents leaked by whistleblower Edward Snowden revealed the NSA’s bulk collection of phone metadata that includes the number called, when the call was made and the length of the call.
The metadata collection programme was authorised by President George W. Bush after the attack on the World Trade Center in New York in 2001.

Under the new plan, the US government would no longer "systematically collect and store records of calling data", and could obtain only records linked to phone numbers tied to legitimate terrorism threats.
But first, these threats would have to vetted by a judge and presented to the Foreign Intelligence Surveillance Court.
Call data would be kept by the phone companies, which would not be required to keep the data for longer than they typically would, reports the New York Times, citing senior administration officials.
The Federal Communications Commission requires telecommunications companies to keep phone records for 18 months, while the NSA currently keeps phone data for five years.
The proposal comes just ahead of the expiry of the current court order authorising the NSA programme, which must be approved by the Foreign Intelligence Surveillance Court (FISC) every three months.
But the US has decided to renew the NSA metadata collection programme for at least one more 90-day cycle, according to reports.
