The end of an era in fashion as Kate Moss leaves the leading high street retailer.

Supermodel Kate Moss has designed her last regular range for the fashion giant run by Sir Philip Green, ending a successful four-year partnership.

Topshop has confirmed that the 14th collection from Moss, the upcoming autumn/winter collection, will be her swansong, although she may feature in a number of one-off designs in the future according to parent company Arcadia, who also owns fellow fashion outlets Dorothy Perkins, Miss Selfridge and Bhs.

Industry insiders claim that the separation has been amicable, highlighted by the opening of the New York flagship store last April when Moss and Sir Philip appeared side by side. It is understood that the considerable amount of time required to put a collection together was the main reason for the departure of Moss, who has chosen to concentrate on other opportunities. Only recently, Ms Moss appeared on the cover of British Vogue magazine, marking the incredible 30th time in her career she has graced the iconic magazine.

The four-year collaboration with Topshop, considered to be a lengthy relationship in the fashion industry, was believed to have netted Moss around £3 million per year. She was snapped up by Sir Philip in 2005 after the tabloid scandal which featured photos of her snorting cocaine, when many thought her career was over. Her last collection will be released in October.

Leading retailer Asda has introduced a new minimum pricing structure on alcohol.

The group has further declared that it will undertake closer working relationships with the UK government to ensure that it is at the forefront of tackling alcohol misuse and abuse across Britain.

The announcement follows the recent high-profile media case of a Tesco store that sold wine for less than cost price in Scotland, leading health campaigners to claim that supermarket chains could not be trusted to be self-policing when it came to the sale of alcohol.

Asda introduced its new alcohol policy on Tuesday, whereby a floor price of duty plus VAT is set on more than 99 per cent of the alcohol sold by the group. This will result in a minimum price of £8.95 for a 20-pack of 440ml 5 per cent strength cans of beer, which would be made up of a duty of £7.62 plus the VAT of 17.5 per cent on top. Similarly, a 750ml bottle of wine would go for a minimum of £1.99 and a one-litre bottle of spirit such as vodka at £10.49.

Asda has also proposed that the government enforce the same policy throughout the entire retail industry in a letter to home secretary Theresa May from chief executive Andy Clarke. Mr Clarke claims that Asda supports a Responsibility Agreement on Alcohol development agreement to ensure that the previously successful partnership between government and industry would not be wasted, and that in conjunction with the OFT, all those involved would be responsible for establishing a safe retail environment which would openly discuss and tackle the issues of alcohol misuse across the UK.
