FORMER prime ministers Tony Blair, Gordon Brown and David Cameron united to remember the former culture secretary Tessa Jowell at Southwark Cathedral for a service filled with laughter and love.

More than one thousand mourners came to pay their respects to the baroness, who was a driving force behind the 2012 London Olympics.

At the service, Dame Tessa’s daughter Jessie recalled her mother’s “endless, heart-bursting, infinite love”.

Mr Blair paid tribute to his friend and former colleague, saying she was “unafraid to stand up for her friends, unafraid to stand up to them, but always standing by them”.

Mr Blair said: “Tessa died with so much still to give, but if life is measured not in how long you live but by how much you give, she lived a length of biblical proportions.”

He ended: “Tessa, we love you, we thank you and we will never, ever forget you.”

Also attending the service were former Labour leader Ed Miliband, former home secretary Lord Blunkett, Mayor of London Sadiq Khan, Commons Speaker John Bercow and London 2012 chairman Lord Coe.

The memorial came as Mr Khan announced a walkway in the Olympic Park will be named in her honour.

Laughter rang out at several moments during the one-and-a-half hour service - as colleagues remembered her insistence on holding multiple meetings and always being on a diet.

A long queue which snaked around the cathedral’s perimeter an hour before the service started was testament to her enduring popularity.

Dame Tessa died in May after suffering from a glioblastoma multiforme brain tumour which was diagnosed the previous year.

A well-liked figure in Parliament, she played a major role in securing the 2012 Olympics for London when she served as culture secretary.

She also championed the SureStart initiative, which aimed to give children the best possible start in life through improvements and better access to childcare, early education, health and family support.

In the months before her death, she moved fellow peers to tears as she used the House of Lords as a platform to discuss her condition and call for patients to have better access to experimental treatment.
