Diageo is to launch a campaign under its Johnnie Walker brand, tied in with its sponsorship of Formula One motor racing, aimed at persuading consumers never to drink and drive.

The Join the Pact campaign, which will be led by Vodafone McLaren Mercedes driver Lewis Hamilton and two-time Formula One world champion Mika Häkkinen, is to be unveiled in Singapore on 30 March 2008. The campaign will be launched initially in Singapore but will then be rolled out across Asia Pacific.

Häkkinen, who is the Johnnie Walker Global Responsible Drinking Ambassador, will be driving a McLaren Mercedes racing-car through the streets of Singapore to kick off the campaign.

Diageo said the launch event, to be held from 4pm - 6pm on 30 March at the Padang, will be Singaporeans' first opportunity to experience a world-class Formula One demonstration given by "a racing legend".

The event will form part of the build-up to the 2008 Formula One SingTel Singapore Grand Prix to be held on 28 September 2008. Members of the public can "join the pact" by signing up at the  www.jointhepact.com website. According to Diageo, those who join stand a chance of meeting Hamilton in Singapore this September.

"Our partnership with Vodafone McLaren Mercedes provides us with a powerful platform to communicate the Never Drink and Drive message," said Ajay Asrani, brand director of Johnnie Walker in Asia Pacific. "In the last three years of our partnership, we have had much success in driving home this message to consumers around the world and we are very excited to be launching this year's regional campaign, Join the Pact, in Singapore."
