The National Gallery in London is to take action against the resale of tickets for its "blockbuster" Leonardo da Vinci exhibition.

The gallery said tickets that have been resold will be cancelled without refund and holders refused admission.

The £16 exhibition tickets are now being resold on eBay and Viagogo for up to £400.

"We are obviously very disappointed at the resale of these tickets for profit," a spokeswoman said. "The resale of tickets for the Leonardo da Vinci exhibition is against the terms and conditions of their sale and this information is printed on the tickets.

"Our website clearly states: 'Tickets that have been resold will be cancelled without refund and admission will be refused to the bearer,'" BBC reported.
