British Prime Minister Theresa May and Prince William led tributes on Monday to Leicester City owner Vichai Srivaddhanaprabha, who was among five people who died in a helicopter crash outside its stadium on Saturday.
Football governing bodies FIFA and UEFA joined in tributes from around the world after the Premier League club confirmed the Thai billionaire was among those to have died.
In a statement, May said: "My thoughts are with those family, friends and supporters connected to the tragic crash outside Leicester City's stadium on Saturday night.
"The outpouring of grief is a testament to how many people's lives were touched by those on board."
Prince William said in a statement released by Kensington Palace: "My thoughts today are with the family and friends of Vichai Srivaddhanaprabha and all the victims of the terrible crash at Leicester City Football Club.
"I was lucky to have known Vichai for several years.
"He was a businessman of strong values who was dedicated to his family and who supported a number of important charitable causes."
FIFA president Gianni Infantino said football's governing body "extends its deepest sympathies" to the victims' families and friends and "to the many football fans for whom Vichai was an integral member of The Foxes family."
UEFA president Aleksander Ceferin said European football "is deeply saddened to hear of the tragic deaths of the owner of Leicester City, Vichai Srivaddhanaprabha, and the other four people who lost their lives."
Vichai took over Leicester in 2010, and was a popular figure among supporters, having overseen the club's unexpected Premier League title victory in 2015/16.
