UK bookmaker William Hill has reported a fall in half-year profits after being hit by changes to betting taxes.
Pre-tax profits fell to British Pound78.7m in the first six months of the year, down 35% from British Pound121.8m a year earlier.
It paid an additional British Pound44m in gambling duties, following changes to the taxation of online betting and fixed-odds betting terminals.
William Hill also said it had bought a 29.4% stake in online lottery firm NeoGames for $25m (British Pound16m).
Shares in the bookmaker had fallen more than 7% by late morning.
In December last year, a new Point of Consumption Tax came into effect, which applies to gambling profits generated from UK customers.
In addition, Machine Games Duty - the levy paid on fixed-odds betting terminals - was increased to 25% in March.
The companys chief executive, James Henderson, said: We have delivered a good operational performance in the past six months during a period of significant regulatory and taxation change for the industry.
Whilst factors such as the Point of Consumption Tax and the increase in the Machine Games Duty rate have impacted our cost base as expected, we continue to progress our strategy and invest in our long-term growth drivers.
William Hills profits were also hit by one-off costs relating to the rebranding of its operations in Australia.
The fall in profit came despite a slight increase in net revenues to British Pound808.1m from British Pound805.2m a year earlier.
The bookmaker also said that the introduction of the governments National Living Wage would cost it about British Pound1m-British Pound2m in 2016.
Referring to William Hills purchase of the stake in NeoGames, Mr Henderson described the online lottery market as an exciting opportunity.
NeoGames business is focused on the US, where lottery spending per head is the highest in the world, William Hill said.
The UK firm also has an option to buy the remaining 70.6% of NeoGames, which it can exercise after either three or five years.
