Simon was joined by his former The X Factor mentor Louis, and Leona, who won the singing contest in 2006, at the British Asian Trust's third annual gala at the Natural History Museum in London.

They spent the evening in the company of other stars including musician Labrinth and comedy actors Sanjeev Bhaskar and Meera Syal to show their support for the organisation, which is one of Charles, Prince of Wales' charities and funds various projects in South Asia.

The event was hosted by TV star Sanjeev, and Leona entertained the 450 guests with a rendition of her international smash hit Bleeding Love and a cover of Cyndi Lauper's Time After Time.

British Asian Trust chief executive Richard Hawkes said after the gala, "This has been a fantastic evening for the Trust. We have felt tremendous support, warmth and encouragement for our work from all of the guests. On this important night, not only did we raise £900,000 for the charity, we also announced our first ever public appeal and partnership to aid Pakistan with the Department for International Development and the Aman Foundation. 2016 will be another exciting year ahead for the British Asian Trust."
