Domino's Pizza has shrugged off the trend for consumer belt-tightening to serve up a surge in UK sales.

The firm's shares leapt around 10 per cent higher as it hailed improved trading in the UK after seeing an 8.1 per cent jump in like-for-like sales in its third quarter to September 24.

This came despite Domino's - which has outlets throughout Cumbria and a factory in Penrith - confirming that Britons remain "uncertain" amid Brexit fears and as the weak pound has squeezed household finances. It thanked a boost from online orders for the sales recovery as it led a concerted advertising push, with internet orders up 17.4 per cent and now accounting for three quarters of all sales.

The UK's biggest pizza delivery chain said its new ad campaign, The Official Food Of Everything, had driven 200,000 online orders on the last Saturday of September alone - the equivalent of 140 orders a minute.

David Wild, chief executive of Domino's, said: "In the UK, consumers are uncertain and they continue to focus on value.

"Our commitment to growth remains undiminished, as does that of our franchisee partners."

The group added that it expects annual profits to remain "at least" in line with City forecasts.

Overall third-quarter group system sales lifted 20.8 per cent - or 11.9 per cent with the boost from the weak pound stripped out - to £286.4m, with international turnover up 25.1 per cent.

Domino's is on track to open a record 90 stores in the UK this year, with more launches already planned for early 2018.
