"There was a suggestion that there was a credible attack on the electricity infrastructure supporting the Games.
The clock was absolutely ticking.
We effectively switched to manual, or had the facility to switch to manual.
It's a very crude way of describing it, but effectively we had lots of technicians stationed at various points."
Security experts have revealed that they received suggestions of a cyber attack targeted at the opening ceremony of last summer's Olympic Games.
Oliver Hoare, head of cyber security for the Games, told the BBC he received a phone call from government listening post GCHQ on the day of the opening ceremony.
There were concerns that the lights in the Olympic stadium could have been turned off during the ceremony.
The threat failed to materialise and the ceremony went off without a hitch, but security officials revealed that they had put extensive precautions in place to withstand such an attack.
Mr Hoare said he" twitched" every time the lights in the stadium dimmed as he watched the ceremony at home with his family.
Couples could soon be able to marry with the Olympic Park as their backdrop. Legacy bosses have applied for a licence to hold civil marriage and partnership ceremonies on top of the "Orbit" - the 260-foot high tower which overlooks the entire park.
The Olympic Cauldron is going on display at the Museum of London.
The award winning cauldron will join other London 2012 objects including Tom Daley's trunks and Bradley Wiggins' yellow jersey.
The search has begun to find a young poet who will perform in and around the Olympic Park.
Aged between 18 and 25 and from London, they will become the London Legacy Development Corporation's Young Poet Laureate for a year and take part in several events.
This would include some big and little moments within the life of the area in Stratford, east London, as the Park reopens in phases a year after the London 2012 Games.
The work of the young poet should reflect "the changing capital" city, the LLDC said.
LLDC chief executive Dennis Hone said: "This programme is part of ambitious plans for arts and culture in Queen Elizabeth Olympic Park and the surrounding area. It is our vision for east London to be a thriving cultural district, and the Park will play a key part in that transformation."
Applications are invited to become one of six young poets who will take part in events and workshops over the summer before the overall winner is named.
More information on the Young Poet Laureate for London can be found online at www.spreadtheword.org.uk.
Applications close on June 24.
Former London Mayor Ken Livingstone hasblamed Labour Chancellor Gordon Brown for the dramatic increase in the budgetfor the London Olympics.
The estimated cost of staging the games rose from £2.2bn in 2005 to £9.3bn in 2007. Mr Livingstone, as Mayor of London was one of the leading figures in Britain's bid, was giving evidence today to the House of Lords Olympic and Paralympic Legacy Committee.
"We had huge problems with Gordon Brown. No Olympics has ever been told to pay VAT before, so that added another £836m, a completely non-sensical decision to have made.
Also, and this was driven very much by the Treasury and Gordon Brown, he insisted on a much larger budget for emergencies and cost over-runs and I was hostile to this."
A third of people wish they had volunteered to help out at last year's Olympics following the success of the so-called Games Makers, according to a study. A similar number said the Games Makers positively changed the way they viewed volunteering, a survey of more than 2,000 adults found.
An estimated 873,600 volunteering hours have been put back into communities by the Games Makers since September, said the report by Olympic legacy charity Join In.
Triple gold-medal winning paralympic equestrian Sophie Christiansen has been awarded her OBE by Prince Charles. She said the award would take pride of place with her gold medals.
"I like to look at my medals and for them to be out for everyone to see, particularly young kids," she said. "I have found that for people to be able to touch and see a Paralympic gold medal is a really special thing so I make sure that I take it in to schools for children to see.
"The slogan for the Games was to inspire a generation and trying to do that is an important part of the legacy."Christiansen said she was not nervous when collecting her latest award because being involved in sport has made her more and more confident over the years.
Prince Charles recognised Laura Trott as he presented the 21 year old with her OBE, saying the athletes had done "really good" work at the London 2012 Games. He asked her if she had to watch what she ate. Trott, still smiling, replied: "No I ate Maltesers."
She said she was nervous but excited about the day, "there is no pressure in this and I got to see my mum Glenda getting ready to go to Buckingham Palace which is not the sort of thing that happens every day." Laura began cycling with her mother, who took up the sport to lose weight.
Trott, 21, made a stunning Olympic debut at the London 2012 Games where she rode away to gold in the omnium and team pursuit.
The dominance of the world-beating trio of Trott, Dani King and Joanna Rowsell, has seen them break the record six consecutive times in the team pursuit.
