The Government must reform the way MI5, MI6 and GHCQ are held to account and "must not continue to bury its head in the sand," civil rights campaigners warned.
Emma Carr, acting director of Big Brother Watch, said:
When a senior committee of Parliament says that the current oversight of our intelligence agencies is not fit for purpose, ineffective and undermines the credibility of Parliament, the Government cannot and must not continue to bury its head in the sand.
This report is a wake-up call to those blindly parroting the line that the UK has the best oversight system in the world.
The law is out of date, the oversight is weak and the reporting of what happens is patchy at best.
The Home Affairs Select Committee wants to see a shake up of the way security and intelligence agencies are scrutinised, starting with the way the Intelligence and Security Committee (ISC) is organised.
Membership of the nine-strong ISC should be elected and the chair should always be a member of the House of Commons.
In addition, it said the ISC chair should always be a member of the largest opposition party.
Under the previous health service structure, primary care trusts would alert all practices in the local area if there was an individual visiting multiple practices to request specific drugs.
MPs have said that the highlighting of so-called 'doctor shopping' now needs to be "formalised" in order for it to continue with the structural changes in healthcare in UK.
A report recommended that NHS England should issue guidance to local clinical commissioning groups (CCGs), so they take on the gathering of data on patients visiting multiple practices to request specific drugs.
There are currently 1.5 million people addicted to prescription drugs in the UK. The abuse of these types of substances is taking place in the shadows and its extent is still unquantified.
Local GPs need to report their suspicions and collate information to illuminate this problem.
– Keith Vaz MP, Committee chair
Lack of action would lead to "catastrophic consequences", Mr Vaz said.
The committee cited work by the All Party Parliamentary Group for Involuntary Tranquilliser Addiction which estimates that 1.5 million people are addicted to these type of drugs, far higher than those who are in treatment for addiction to illegal drugs.
Around 6% of public tip-offs about illegal immigration lead to an investigation and only 1.5% results in a person being removed from the country, according to a Home Affairs Select Committee report.
The report also said the now-defunct UK Border Agency (UKBA) had a backlog of 432,029 immigration and asylum cases when it was scrapped at the end of March, which at current levels will take five years to clear.
