But a spokeswoman said: The UK has faced serious threats from terrorism for 30 years and has always had protective arrangements

But a spokeswoman said: “The UK has faced serious threats from terrorism for 30 years and has always had protective arrangements.”Bob Knights, who is leading the conference, said there had been no input from intelligence services. He is the former head of the Designing Out Crime Association and a former Metropolitan Police officer. He said: “This is the first event of its kind in Britain and we felt the need for a special day to focus on the threat of terrorism.”Among issues addressed will be assessing risk, such as what the building is, who will work there and was it next to any potential targets, he said. There will be also discussions on structures, emergency planningand how air vent systems could limit risks.. Scotland Yard said yesterday that lone terrorists unconnected with al-Qa’ida could use the anniversary of the 11 September attacks to commit their own bombings in Britain. The head of the Metropolitan Police’s anti-terrorist squad, Assistant Commissioner David Veness, said there had been no specific threat to Britain and urged people to behave normally next week.The security services and police will also keep Islamic extremists under surveillance.

The undisclosed number of suspects represent what anti-terrorist officers believe is a small pool of support for extremist groups who could be capable of further attacks.Mr Veness said the focus was not only on potential al-Qa’ida attacks, but those who might attack “because of the publicity it represents”.He said: “We shouldn’t just think about the ghastly spectacular happening, but also the range of possibilities that smaller groups and individuals may use.”There may be individuals who think here is an anniversary which is a world stage in terms of publicity and for their own reasons they might attack. We shouldn’t underestimate these individuals.”Businesses in the City of London have been extensively briefed in recent weeks, as have other police forces across the country. Security will be in place for memorial events and Jewish holidays that fall over the 11 September period.Mr Veness said “dramatic” progress had been made with counter-terrorism operations in the past 12 months. Since September 11, extensive work had been done on the threat posed by suicide bombers in Britain.He said while public attention was on international terrorism the threat from Irish Republican dissidents was “not forgotten”.Since 11 September, Scotland Yard has received 8,000 requests for assistance from the Federal Bureau of Investigation. Mr Veness said: “By any comparison, this has been the busiest 12 months of counter-terrorism anyone can recall.

Barriers have crumbled in the pursuit of the overwhelming public good.”. Baroness Young, the former Conservative cabinet minister and a vociferous campaigner against gay adoption and the abolition of Section 28, has died at the age of 75. She emerged as a fierce opponent of the John Major government’s highly contentious “no-fault” divorce legislation and was a leading voice in the campaign against abolishing Section 28 and lowering the homosexual age of consent.She came a life peer in 1971 and was the first woman to lead the Conservatives in the Lords. Iain Duncan Smith, the Conservative leader, said: “I have always had huge admiration for Janet’s courage, conviction and tenacity. She was a principled campaigner in the Lords and in the wider country, tirelessly fighting for the causes in which she believed.”In an age when style so often seems to come before substance, Janet Young epitomised the timeless value of staying true to one’s own personal beliefs.”Baroness Thatcher said: “Janet Young was not only a good friend but she was one of the most courageous and effective woman politicians of her generation. She devoted her whole life to public service, and public life is diminished by her loss.”Lord McNally, deputy leader of the Liberal Democrats in the Lords, said: “Her strong views on personal morality often brought her into conflict with those of a different outlook. But no one ever doubted either the strength of her convictions or the integrity with which she held them.”The gay rights campaigner Peter Tatchell said she had “poisoned society with prejudice and intolerance”.
