The company which makes the fruit drink Ribena has been found guilty of misleading advertising after two New Zealand schoolgirls proved there was hardly any trace of Vitamin C in its product.

Glaxo Smith Kline was fined over €120,000 by New Zealand's Consumer Commission, who accused the company of a 'massive breach of trust'.

The issue came to light following a TV advertisement which claimed that the blackcurrants in Ribena contained four times as much Vitamin C as oranges.

Following this, two schoolgirls tested ready-to-drink Ribena and found it contained almost no Vitamin C at all.

After being found guilty of misleading advertising, Glaxo Smith Kline said that the Vitamin C in the Ribena in question had degraded by the time it was tested.

And it claimed that the Ribena sold in Ireland does contain all the Vitamin C levels promised on the label.

It was not the first time that the makers of Ribena had been upbraided for misleading the public.

In 2001 a London court forced the company to withdraw a claim that Ribena did not encourage tooth decay.
