The organisation also predicted that 2013 sales will come in above previous expectations. The SMMT said new car registrations rose to 163,357 in April, a rise of 14.8% compared to a year ago, although this was in part due to a higher number of sale days this year. The figure was driven in part by private registrations, which were up almost a third on April last year. In other UK economic news, shop price inflation fell to its lowest level in three and a half years in April, the British Retail Consortium (BRC) has reported. The figure declined to 0.4% from 1.4% in March, with food inflation dropping to 2.9% from 3.5% month-on-month and non-food falling to deflationary territory, down 1.0% in April after a 0.2% rise the previous month.Elsewhere, new research has shown that as many as one in three people will be forced to reduce the amount they put into savings over the coming months as a result of mounting pressure on personal finances.
