illegal wildlife trade.

Leaders from 40 states are gathering in London to discuss the illegal wildlife trade.The aim is to draw up a global declaration that will tackle animal trafficking.Conservationists believe there are just 3,200 tigers left in the wild.

Interpol, the international intelligence agency, which will also be present at the meeting, says most of this being driven by organised crime syndicates, who have moved from narcotics and guns onto wildlife.

Much of the demand comes from Asia, where animal products, such as rhino horns, are used in traditional medicine or are bought by the rich as trophies.Delegates from China and Vietnam will be attending the meeting, held at Lancaster House on Thursday.They will be joined by representatives from African states, where a lot of the poaching takes place.
