Why are England players wearing black armbands in T20 WC 2022 final against Pakistan?

England players are wearing black armbands in the T20 World Cup 2022 final against Pakistan. This is in tribute to David English, who died aged 76 following a heart attack. David was founder of Bunbury Festival, an annual cricket tournament for Under-15 players. The festival has helped foster careers of 1,000 first-class cricketers in England, including 125 international cricketers.
