The two-year deal begins with this year's championships which get under way next Sunday (March 27) at the French resort of Meribel.

It is one of the key events on the 2010/11 British ski calendar and is open to competitors from around the world.

David Edwards, chief executive of British Ski and Snowboard, said: "Delancey's help will extend beyond backing for these Championships - it will also provide some funding to help our Alpine athletes to develop and compete on a world stage."

Jamie Ritblat, chairman and chief executive officer of Delancey, said: "As an investor and developer in the property sector we are committed to ensuring we make a positive contribution to the younger generation, the UK wider community, and our collective environment.

"The British National Alpine Ski Championships is one of the most important dates on the British ski calendar and provides many of the country's younger racers with their first opportunity to compete on snow against a top class field.

"We are proud to be involved with such a prestigious event and pleased we can play our part in providing much-needed support for a competitive Olympic sport that the British have been a leading force in for over 100 years."
