Andy Murray has signed a petition calling for a crackdown on wildlife crime in Vietnam.

The world number one is an ambassador for wildlife charity WWF and has added his name to a 155,000 signature petition calling for an end to the country's illegal wildlife trade.

The move comes less than a week before the Hanoi Conference on Illegal Wildlife Trade, taking place in Vietnam on November 17 and 18.

Murray said: "I have just signed the WWF petition to urge Vietnam to end its illegal trade in wildlife products.

"Some of the world's most beautiful species are threatened by this horrendous crime - from tigers to pangolins to elephants to rhinos.

"It's up to each one of us to do our part and take a stand against it so I encourage everyone to sign this petition."

The Duke of Cambridge will be attending the conference along with governments from around the world.

The petition launched by WWF will be presented to the Vietnamese government next week.

Last year, poachers killed 1338 rhinos and around 20,000 elephants across Africa to feed the relentless and illegal trade in horns and ivory.

Vietnam has the largest illicit market in the world for rhino horn and also plays a key role in the trafficking and consumption of large amounts of other illegal wildlife products including ivory, pangolin scales and tiger skin
