London (AP): Prime Minister Gordon Brown was outlining the first major overhaul of Britain's national security plans since the end of the Cold War on Wednesday, aiming to curb threats including extreme weather, pandemic diseases, unstable energy supplies and terrorist attacks, his office said.

Brown is publishing Britain's first-ever national security strategy and reorganizing the county's response to a host of natural and human threats, his spokesman Michael Ellam said.

Almost three years after the July 7, 2005, attacks on London's transit network, which killed 52 commuters and the four bombers, Brown planned to indicate that climate change and scarcity of natural resources could pose as great a threat to the U.K. as terrorism.

Brown may sanction greater access of public records, including CCTV footage and public transport data, for police and security officers _ a move aimed at providing a greater ability to track suspected terrorists, but likely to be opposed by civil liberties campaigners.

Analysts and think tanks have long expressed concern that Brown's government has placed too much emphasis on counterterrorism and ignored the risks posed by climate change, failed states and disease.

``We face different threats than we faced 10 or 20 years ago and those threats are complex and they require complex solutions,'' Ellam said.

Richard Mottram, Brown's chief adviser on intelligence and security until last year, warned in December that risks of a global flu pandemic, the impact of mass global migration and threats from organized crime were receiving too little attention.

Terrorism minister Adm. Alan West, a former head of defense intelligence, said the new strategy will take account of progress in combatting terrorism, including a doubling of funding for counterterrorism since 2001 to 2.5 billion pounds (US$5billion; euro3.2billion).

``I can put my hand on my heart and say that in the last year, though the risk hasn't gone away, we are safer than we were a year ago,'' West told British Broadcasting Corp. radio.

Under the new strategy, the heads of Britain's domestic intelligence service MI5 and overseas intelligence service MI6 could be required to detail the work of agencies in public for the first time.

Parliament's Intelligence and Security Committee, which scrutinizes the work of Britain's security services, has previously met only in private but may hold future public hearings.

Brown will stress the need for better coordination between the military, police, intelligence agencies and diplomats to respond to security risks, Ellam said.

He is expected to call for changes to the Joint Terrorism Analysis Center, a combined intelligence and defense service that provides assessments on the terrorism threats.

But Brown will not back demands from opposition lawmakers to establish a U.S.-style National Security Council, proposing a new forum of security experts, West said.

``It's a bold move by Gordon Brown and his government to set out a first security strategy,'' said Charlie Edwards, a security analyst at the London Demos think tank. ``Change is needed.''

Brown's strategy is also likely to call for quick progress on expanding the number of permanent members of the United Nations Security Council and suggest a targeted use of aid money to help shore up fragile states, government officials said.
