National treasures which make England great are being celebrated by the creation of a list of English icons. Among 21 new icons added to the list on Friday is Morris dancing.

The list, compiled by ICONS - A Portrait of England, features people, buildings, works of art and literature, events, landmarks and activities such as the sport of cricket.

The first twelve icons were announced in January and included the FA Cup, the Spitfire, London buses and a cup of tea. Blackpool Tower is among the 21 added to the list now.

The Notting Hill Carnival started in 1964 and has become the largest street carnival in Europe. Its contribution to the English calendar is marked with icon status.

The list is formed from nominations and votes from the public. Jane Austen's Pride and Prejudice, pictured in a 1990s BBC TV adaptation, received enough votes to make the line-up.

Hadrian's Wall, 73 miles long and stretching from the Tyne to the Solway Firth, was built on the orders of Roman Emperor Hadrian "to separate the Romans from the barbarians".

But the quality of more modern structures is recognised too - the Eden Project conservation site in Cornwall, which opened in 2001, is also handed English icon status.

More icons will be added to the list throughout 2006 until it reaches a total of 100. Big Ben - actually the principal bell inside the famous Westminster clock tower - is included.

Admiral Horatio Nelson's HMS Victory was launched in 1765, played a decisive role in the Battle of Trafalgar in 1805 and now sits in dry dock at Portsmouth Historic Dockyard.

The mini-skirt is seen as symbolising the Swinging Sixties and women's liberation. Daring at the time, the mini-skirt is modelled here by a woman with patriotic taste in carrier bags.

The pub has been a familiar feature of England's landscape since the 13th Century, when it was often safer to drink beer than water. It claims its place on the list of English icons.
