The daughter of former US President Bill Clinton and Secretary of State Hillary Clinton has married her long-term boyfriend at a lavish ceremony.

Chelsea Clinton and investment banker Marc Mezvinsky tied the knot at the Astor Courts estate in New York state.

A no-fly zone was imposed to stop film crews taking aerial shots of the nuptials.
