A University of Leeds graduate and her two young children have been killed in the Sri Lanka terror attacks.
Anita Nicholson, 42, is a Leeds law graduate and former senior legal adviser to the Treasury.
She had been living in Singapore since the start of 2019 where she worked for mining and metals firm Anglo American.
Mrs Nicholson was killed as she ate breakfast at the Shangri-La hotel in Colombo with her family.
Her young children, 14-year-old son Alex and 11-year-old daughter Annabelle, were also killed in the attack.
Her husband Ben survived.
Paying tribute, Mr Nicholson, a 43-year-old lawyer, said: "Anita was a wonderful, perfect wife and a brilliant, loving and inspirational mother to our two wonderful children.
"The holiday we had just enjoyed was a testament to Anita's enjoyment of travel and providing a rich and colourful life for our family, and especially our children."
"Alex and Annabel were the most amazing, intelligent, talented and thoughtful children and Anita and I were immensely proud of them both and looking forward to seeing them develop into adulthood.
"They shared with their mother the priceless ability to light up any room they entered and bring joy to the lives of all they came into contact with."
The Sri Lankan terror attacks, which targeted churches and hotels on Easter Sunday, killed more than 320 people - including 45 children and eight Britons.
