British bookmaker William Hill said it expected operating profit this year to come in at the top end of market forecasts after the soccer World Cup helped boost its third-quarter results. 

The figures are a boost for new chief executive James Henderson, who took the top job in August after almost three decades with the company. 

The company said its net revenue rose 23% in the 13 weeks to the end of September and operating profit jumped 89%. 

"The group performed strongly in Q3 driven by both favourable sporting results and the continued development of our UK and international businesses," Henderson said in a trading statement.

"Positive sporting results in the quarter, including a strong end to the World Cup, have moved us close to or ahead of normalised gross win margins on a year-to-date basis," he added. 

Bookmakers had been forced to make big payouts earlier in the year on weekends when a number of the top teams won in the English Premier League, hurting their margins. 

This was offset by a positive World Cup when William Hill reported an 80% increase in sums wagered compared with the 2010 tournament. 

William Hill said it expected operating profit to be towards the top of a range of between £341-366m for the year as a whole. 

The bookie chain has expanded online and internationally, adding operations in Italy, Spain, Australia and the US to complement its chain of Irish and UK high street betting shops. 

The betting industry is facing financial and regulatory pressures in Britain where the government is tightening controls on betting shops and increasing taxes on both online gambling and high stakes gaming machines. 

The measures are expected to cost the industry almost £400m a year and are likely to depress profits from 2015, despite cost cuts planned to soften their impact.
