Former Prime Minister of Great Britain and Northern Ireland and Executive Chairman of the Tony Blair Institute for Global Change
"Tessa had passion, determination and simple human decency in greater measure than any person I have ever known. She was an inspiration to work with, and a joy to be near. She was the most wise of counsellors, the most loyal and supportive of colleagues, and the best of friends.
"What she achieved was remarkable. She was the first senior politician fully to understand the importance of public health and to shift health policy towards prevention of illness and not only cure. She was the instigator of Sure Start and in the process gave hope and opportunity to hundreds of thousands of children. She brought the 2012 Olympics and Paralympics to London, and ensured their success. Whatever task she was set she gave her all, touching hearts and minds with her gentle compassion and sympathy.
"There was no one like Tessa and no one better. I will miss her more than I can say. My thoughts and prayers, and those of Cherie and all the family, are with David and her wonderful family of whom she was justly very proud."
