What will 7/7 inquest achieve?
The inquests has been delayed while three friends of the bombers were tried and cleared of any involvement in the attacks on three underground trains and a bus.
Lady Justice Hallett will preside over five months of hearings without a jury. She will look at whether MI5 could have stopped the bombers - but many victims' families still want a public inquiry.
The inquests are expected to open with the hearings being shown footage and pictures of aftermath of the attacks that have never been seen before.
What will the inquests achieve? Should there be a public inquiry? Will new footage help unveil the story?
