The firm, Entain, also owns high street bookmaker, Coral
Ladbrokes and Coral owner Entain has seen profits surge as lockdown restrictions eased and a full sporting calendar returned.
Much of the growth came through online gambling, with high street bookies remaining closed due to Covid restrictions, the company said.
Online net gaming revenue was up 28%, while revenues from high streets was down 46% in the first six months of the year.
