"A two-minute silence is among public and private events to mark the first anniversary of the London bombings. "
'The UK is preparing to mark the first anniversary of the London bombings that claimed 52 lives and injured hundreds.
At 0850 BST - when bombs on three Underground trains went off - flowers will be laid at King's Cross station, near the scene of one of the attacks.
At midday, a two-minute silence will be observed across the country, including Wimbledon and other events.
A public ceremony will be held later in Regent's Park, with readings and a recital of the names of the dead.
The commemoration comes as Metropolitan Police Commissioner Sir Ian Blair gives a firm warning that London must expect another attack.
