Days after observing a minute's silence for the victims of the Tunisia beach massacre, the country will fall silent again in memory of the 52 people killed in the 7/7 atrocity in London a decade ago.

The period of reflection - to take place at 11.30am on Tuesday during a service at St Paul's Cathedral attended by the Duke of York - will be observed across the capital's public transport network.

Announcements will be halted and bus drivers asked to bring vehicles to a stop if they can do so safely.

Survivors, relatives of the dead and members of the emergency services have been invited to the commemorative event.

Wreaths will be laid beforehand at the permanent Hyde Park memorial to the outrage, where a second service, to be attended by the Duke of Cambridge, will take place later, featuring music, a series of readings and the laying of flowers.
