The balance between security and privacy again came into sharp focus yesterday when emergency legislation was brought forward requiring internet and telephone providers to retain records of our calls and emails.

For me, the broad agreement between the three main parties on what can sometimes be a really divisive issue was striking.

The legislation is needed to protect us all – including those who oppose it because they say it will invade people’s privacy.

The powers it covers are not new but our ability to use them has been lost due to a recent judgement by the European Court of Justice on an European Union-wide directive. However, the British law which was affected was a narrower, more proportionate and regulated provision for data retention and investigatory powers.

Under the new data retention and investigation powers bill our police and security services will be able to continue to access data to help keep us safe – from terrorists, from organised crime, from paedophiles.

It will save some lives and stop others from being shattered, be it a mum who has lost a leg in a terrorist bomb attack, or a child who has been abused.

I make no apologies for using such emotive language, because I know as a member of parliament’s Intelligence and Security Committee that these are just the kind of scenarios prevented by these existing powers.

Of course, people do not hear about these threats at the time, but the terrorist plots and crimes that do succeed should be warning enough of the dangers if we do not act now.

These powers are used in 95 per cent of serious and organised crime prosecutions.

They were used in investigating some of the 19,000 reports of child abuse received last year by the Child Exploitation and Online Protection agency.

They enabled police to find out about the attempted terrorist attack at Glasgow airport in 2007. And they enabled our security services to check who the murderers of Lee Rigby had contacted to ensure no further attacks were planned.

The powers enable data to be gathered about the time of phone calls and emails, the location from which they were made and sent, and the identity of the sender and recipient.

But this data is only accessed when there is a suspicion it could relate to terrorist or criminal activity.

The content can only be looked at further when a legal intercept is approved and a warrant signed by either the foreign secretary or the home secretary.

It is simply wrong to think the authorities routinely access all of our private correspondence on a whim, or just to be nosy, as is implied by some of the headlines.

Would any of those who claim this invades their privacy complain if their life was saved by these vital powers?

The legislation governing them is a stop-gap which will expire in 2016. In the meantime parliament will have the chance to scrutinise the issue in more detail, and there will be new safeguards in place.

Labour has helped to secure an independent review of the Regulation of Investigatory Powers Act which governs data access and retention to ensure it keeps pace with technological advances.

There will be annual transparency reports on the use of the powers and a new privacy and civil liberties board akin to that in the United States will be set up to ensure that these considerations are taken on board when government policy on counter-terrorism is drafted.

I share some of the concerns raised about the speed with which the government is asking us to turn around this legislation. But terrorists and serious criminals will wait for nothing or no one in their plans to do us harm. So the alternative of our intelligence and law enforcement agencies being unable to obtain vital and sometimes life-saving information would be disastrous.

When I was the counter-terrorism minister at the time of the 7/7 bombings I saw for myself the trauma caused to innocent people and their families.

I share the views of most people in our country that our agencies must have the power to disrupt plots and bring the perpetrators to justice – while at all times acting lawfully, proportionately and in accordance with human rights.

It is a difficult balance, but one which must be struck.
