Mrs Blair was at the Asian Women of Achievement Awards to present the Professional of the Year honour to Professor Faraneh Vargha-Khadem, who is the head of Developmental Cognitive Neuroscience at University College London.
"The reason why people are here tonight is because they, like myself, are so proud of what we do here in Britain to celebrate a multi-cultural community," said Cherie. "The fact we can all get together here and celebrate the achievements of so many different Asian women from all sectors of society, celebrating their differences and achievements, is absolutely fantastic."
She was joined at the ceremony by the Aga Khan's wife, Her Highness Begum Inaara Aga Khan.
