UK inflation rose for the first time in five months over the Christmas period, driven by higher tobacco prices following tax rises announced by the chancellor and a sharp increase in airfares, according to official figures. Data published on Wednesday by the Office for National Statistics showed that consumer price inflation climbed to 3.4 per cent in December, up from 3.2 per cent in November and above economists' expectations. It marked the first increase in inflation since July last year and keeps price growth well above the Bank of England's 2 per cent target.
