The manager at Altham-based card firm Hambledon Studios was on the number 30 bus in Tavistock Square when a bomb exploded, killing her instantly.

Former Hyndburn Council leader Peter Britcliffe yesterday said people will continue to remember Mrs Hartley, 34, and must continue to learn lessons from the barbaric events.

He said: “It was a very sad and shocking time 10 years ago when Marie was killed.

“Tavistock Square is part of London I always go to when I visit, and I always think of that tragic moment when I’m there.

“Ten years on, as recent events in Tunisia show, we are still at heightened risk of terrorism, and we all still need to be vigilant.

“You never know when or where they are going to strike.”

Mrs Hartley and her colleague Camille Scott, from Preston, were heading to an exhibition in Islington, and had boarded the bus after earlier bombings at Edgware Road, King’s Cross, and Aldgate forced the closure of the tube network.

They just sent messages to loved ones saying they were fine when Hasib Hussain detonated his device.

In total, 52 people were killed and hundreds of others injured, some seriously.

Survivors of the bombings will be joined by relatives, the prime minister, London mayor Boris Johnson, other politicians, and members of the emergency services at memorial events today .

The terror attack in Tunisia, another Islamist extremist atrocity which claimed the lives of innocent Britons and injured two Darwen women, is likely to make July 7 all the more poignant for many.

Married to David and with two children, Liam and Adan, Mrs Hartley was described by her family as a woman who had achieved ‘so much in so few years’.

Her late father, John Targett, said before his death: “It was a barbaric act that achieved nothing.”
