Takeaway food ordering website Just Eat raised its revenue expectations to slightly above £240m (€337m, $370m), up from the £230 million guidance issued in August.

"The strategy of ongoing investment in technology and marketing to drive order growth has delivered orders ahead of management expectations with an acceleration in order momentum over the period," the company said in its third-quarter order report.

Poor weather had helped the company's order growth accelerate marginally over the summer, the statement said, adding that more than 74 per cent of those orders were made via mobile devices like phones or tablets.

The company has also bought two small businesses in Canada and Northern Ireland, it said. "Our strategy of investing in technology and marketing to drive growth has delivered orders ahead of management expectations with an acceleration in order momentum," the company's chief executive, David Buttress said.
