Domino's Pizza has seen its share price soar 14% today (Wednesday) after revealing that its full-year profits are set to beat expectations.

The pizza giant said like-for-like sales in the UK in the third quarter of 2015 were up by just under 15% to £200 million.

Domino's said it was boosted by "robust" increases in online sales, which were itself driven by a surge in orders from its mobile app. Online sales were up 35% in the quarter compared with the same period last year. And three quarters of all sales made so far this year have been completed online, half of which have come through its app.

The pizza chain highlighted the success of its sponsorship with Channel 4 television programme Hollyoaks in boosting sales. And it thanked "the relatively poor weather in the summer months".

Domino's opened 12 new stores in the UK during the quarter, taking its total for the year to 33. It has previously said it will open at least 50 new stores in the UK this year.
