Aiyawatt Srivaddhanaprabha has pledged to continue his late father’s “big mission” in Leicester and do everything in his power to carry out his vision and dreams.

Speaking four days after the helicopter crash that killed the Thai billionaire Vichai Srivaddhanaprabha and four others following Leicester’s game on Saturday, his 33-year-old son – the club’s vice-chairman – acknowledged the businessman’s legacy and paid tribute to all those who have mourned his passing, indicating that he will honour his father’s memory by continuing his work.

“I would like to thank everyone from the bottom of my heart for this overwhelming support,” Aiyawatt, generally known by his nickname Top, said in a statement that suggested he would play the leading role at the club. “Thank you also to Leicestershire police and the emergency services, for their fast response and their professionalism and sensitivity.

“What happened made me realise how important my dad was to many people all over the world. I am touched by how many people kept him close to their hearts. I am extremely proud to have such an extraordinary father and nothing would make him prouder than to see how the Leicester City family that he built is supporting each other through a time of such sadness. He loved his family and he made Leicester City into a family.

“From him I have received a very big mission and legacy to pass on and I intend to do just that. I will do everything I can to carry on his vision and dreams. I know that I will receive the support I need to make this happen and I am so grateful for all the messages and kind words.

“My family and I would like to thank each and every one of you for your sincere kindness and good intentions during the most difficult time for us. I miss you Dad, with all my heart.”

Vichai’s wife, two sons and two daughters are on the executive board of the King Power company he founded.
