Record-breakers in the news today

Former UK Prime Minister Margaret Thatcher has died at the age of 87 after suffering a stroke.

Lady Thatcher was Conservative prime minister from 1979 to 1990 and was the first woman to hold the role.

She also held the record for the longest-serving British Prime Minister of the 20th century, having been in office for 11 years and 208 days from 4 May 1979 to 28 November 1990.

Scientists have come up with a way to cut half the fat from chocolate.

Researchers at the University of Warwick have developed a process for creating the confectionary that uses fruit juice instead of fat, yet still managing to retain its "chocolatey" feel and taste.

The world’s best-selling chocolate bar is Cadbury’s Dairy Milk, generating annual sales worth $852 million worldwide.

It is especially popular in the UK – the British are the second largest per capita consumers of chocolate in the world (after the Swiss), getting through an average of 8.6 kg (19 lbs) per person every year.

English Premier League football team Manchester United have today announced a £15m-a-season deal that will see the club’s Carrington training ground renamed the Aon training complex.

The eight-year deal, which starts in July, gives the American insurance giant the right to display its logo on training kit for friendly and competitive domestic fixtures.

The longest ongoing sponsorship of a professional football competition is 20 years, achieved by J.League Yamazaki Nabisco Cup (Japan), on 3 November 2012.

Finally, horror remake Evil Dead has proved a hit with movie fans after earning $26m (£17m) in its opening weekend at the US box office.

Directed by Fede Alvarez and produced by Sam Raimi - who also wrote and directed the 1981 original, it tells the gory story of a group of five twenty-something friends who are terrorised by and possessed by demons during a trip to a cabin in the woods.

Despite the opening weekend success, the Evil Dead franchise has some way to go before it matches the success of another scary series of movies.

With a total worldwide gross of $733 million (£481 million) over its first six instalments, the Saw franchise holds the record for the world's most successful horror movie series.
