England is part of the United Kingdom of Great Britain and Northern Ireland. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies to the north west of England, whilst the Celtic Sea lies to the southwest. The North Sea to the east and the English Channel to the south separate England from continental Europe. The country covers much of the central and southern part of the island of Great Britain, which lies in the North Atlantic; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight.
