MCV reports on ChartTrack figures which indicate that Sony's PSP endured its worst ever week of sales in the UK last week.

The poor sales figures have been blamed on the imminent arrival of the slimmer and lighter model. Sony told MCV that retailers are "thinning out" stock of the original PSP to make way for the new model which is released in the UK on September 14.

ChartTrack data indicates that calendar year PSP sales are currently 32.1% down on what they were at the same time last year.
