Some of the nation's most popular hot drinks are fuelling an obesity crisis, health officials sayiStock

Hot drinks containing "shocking" levels of sugar are being sold by popular high-street chains, according to a campaign group as Starbucks, Costa and Caffè Nero are accused of stoking a national obesity crisis by selling sugar-laden beverages.

Research by Action on Sugar found a third of the nation's favourite hot flavoured beverages contain the same or more sugar than a can of Coca-Cola, with some having a staggering 25 teaspoons of sugar – three times the recommended daily intake.

The worst offender was a large, or 'Venti', version of Starbucks' Hot Mulled Fruit Drink, which comes in either grape with chai or orange and cinnamon flavour. The drink contains 99g of sugar, the equivalent of eating five muffins.

Costa's largest Chai Latte contained the next highest level, at almost 80g, while drinks from KFC and Caffè Nero also featured in the list of top 20 worst offenders. The organisation's research said 98% of the 131 hot flavoured drinks found in the high-street chains would carry the Food Standards Agency "red" warning label for excessive levels of sugar.

Here is the full list of the worst offenders, according to the research carried out by Action on Sugar (the recommended daily intake of sugar for adults and teenagers is 30g/seven teaspoons):
