The wealthy are being urged to follow the lead of Lord Sainsbury.

The philanthropic Tory peer has made a £25 million donation to the British Museum, in what could herald a new shift in funding.

The culture secretary, Jeremy Hunt, called on the rich of Britain to do more to fund the preservation of cultural institutions on Sunday, after the Lord Sainsbury pledge has outstripped government funding on its own. Hunt said that the government did not wish to rely on the generosity of private individuals to fill the funding gap in the culture budget, which has been shaved by 25 per cent, but added that he hoped more like Lord Sainsbury would come forward to help bankroll national institutions.

The donation, which was the largest in Britain since the National Gallery was given £50 million in 1995 by Sir Paul Getty, naturally delighted museum officials who have been anxiously awaiting on news for how to go about managing their own funding cuts.

The money from the donation will go towards a new Lord Rogers-designed £135m exhibition space and conservation centre, which will house temporary, blockbuster shows and play home to specialist conservation laboratories. Popular exhibits, including the soon to be released Book of the Dead show on Egyptian antiquity, are currently displayed in a temporary viewing area inside an old reading room. The government had initially promised to donate 22.5m for the new facility, with around 70 per cent of the funding target now met.

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.
