British baker and fast-food chain Greggs this week introduced a further round of price rises, including for the sausage rolls it is famous for, as it battles rising costs, its boss said on Tuesday. "We have put a small number of rises across products as of yesterday, we've worked hard to mitigate that," Chief Executive Roisin Currie told Reuters. She said a Greggs sausage roll was 1.05 pound ($1.20) at the start of the year, moved to 1.10 pound in May and is now 1.15 pound. The bakery chain wrote in a tweet: “Like many other retailers, we’re having to manage the pressure of rising prices across our supply chain. We’ve had to make some small price increases across our range.” Rising costs of raw materials, production, labour and energy have all impacted the chain, forcing it hike the prices of its food to absorb some of the costs. However, the chain said its low-cost meals were appealing to people who are struggling amid the current cost of living pressures.
