Almost 90% of people would support increased security checks at borders, airports and transport hubs, according to a survey.

While 89% would back more stringent checks, 64% said such measures were vital ahead of the Queen's Diamond Jubilee celebrations and the London Olympics.

In addition, 77% would support the installation of body scanners and 75% would back biometric checks such as fingerprinting, the survey by information technology company Unisys found.

The survey of more than 1,000 UK adults was conducted in February - before the recent problems of long immigration queues at Heathrow Airport.

The poll also revealed that 79% would like to see enhancements in the way information is shared between governments and security services to ensure public safety during this summer.

"The UK is a world leader in aviation security," said Darren Caplan, chief executive of the Airport Operators Association.

He went on: "UK airports are already carrying out the highest standards of security checks for passengers departing the UK, and our airports will be applying the same rigorous security checks at search areas during the Olympic period.

"Airports work actively with the Government on long-term plans for the use of body scanners at UK airports, and of course there is potential for them to play a part in overall security arrangements at Olympic venues. The user experience is key and it's important to choose equipment that meets people's needs, as well as enhancing security, when using this rapidly evolving technology."

Neil Fisher, vice president of global security solutions for Unisys, said: "As planning for this summer's events hits fever pitch, we need to take into account the call from UK citizens to strengthen our security, both at points of travel and at entry into public venues.

"The need to define a holistic security strategy and integrate different agencies, technologies and sources of intelligence is vital.

"With around 120 heads of state set to visit the UK this summer, along with over a million visitors to the Olympics alone, there is a real opportunity for the UK to demonstrate how this can be delivered effectively and provide a blueprint for other countries hosting similar events."
