Hilton fortune to go to charity

Paris Hilton spent three weeks in jail earlier this year

The inheritance of US heiress Paris Hilton looks set to shrink dramatically after her grandfather announced plans to give most of his fortune to charity.

Hotel magnate Barron Hilton, 80, will donate 97% of his $2.3bn (£1.2bn; 1.6bn euros) fortune to the Conrad N Hilton Foundation, set up by his father.

The funds come from the $20bn sale of Hilton Hotels to The Blackstone Group.

Reports have said that Mr Hilton is embarrassed by the behaviour of his granddaughter.

Ms Hilton, known for her party lifestyle, spent three weeks in jail earlier this year for violating probation in a drink driving case.

Mr Hilton will give $1.2bn immediately to a charitable trust that will eventually benefit the foundation.

The rest of the money will follow after his death.

The foundation supports projects that provide clean water in Africa, education for blind children and housing for the mentally ill.
