The Duchess of Sussex was joined by her mother at a Kensington Palace reception to launch a Grenfell cookbook.

Following the catastrophic Grenfell Tower fire past year, a group of women gathered in a communal kitchen at the Al Manaar Muslim Cultural Heritage Centre in West London, where they could prepare fresh food for their families, friends and neighbours.

Meghan continued: "Through this charitable endeavour, the proceeds will allow the kitchen to thrive and keep the global spirit of community alive".
And Munira Mahmud, 34, also managed to escape the burning building, leading the rest of her family - including her husband, his father and their two children to safety.
