Investigatory Powers Bill

Debate between David Davis and Lindsay Hoyle

Report: 2nd sitting: House of Commons
Tuesday 7th June 2016 Commons Chamber

[Mr David Davis (Haltemprice and Howden) (Con)]

rose—

[Mr Deputy Speaker (Mr Lindsay Hoyle)]

Order. I know that the right hon. Member for Haltemprice and Howden (David Davis) is very good at whistling, but I am sure that shadow Ministers do not respond to whistles, and that the hon. and learned Member for Holborn and St Pancras (Keir Starmer) wanted to give way to him anyway.

[Mr Davis]

I was not intending to be discourteous, Mr Deputy Speaker.

The hon. and learned Gentleman said that it was not possible to screen out the correspondence of the various privileged groups he described. The issue arose at the Investigatory Powers Tribunal in respect of one of the Wilson doctrine cases, and that was the assertion made by the Government barrister at the time. However, I consulted a number of experts, including Ross Anderson at Cambridge, and they said that it was perfectly possible. A great deal of screening is already done to take out dross—issues such as pornography—and it is perfectly possible to screen out targeted groups as well.
