The British Tourist Authority is inviting British residents to send a special invitation to their friends and relatives living overseas and enter a prize draw to win them a free flight, hotel accommodation and other travel deals.

At the launch of the BTA's second phase of the UK OK campaign, people are urged to phone hotline number 0844 477 8366 for a free competition pack or log on to www.visitbritain.com/UKOK.

In addition to postcards, the invitation pack contains a Hidden Britain brochure, a CD-ROM of Britain, a UKOK badge and a UKOK pen to write the cards.

The initiative is supported by the ETC, visitScotland and the Welsh Tourist Board; material in the campaign will be specific to these parts of Britain.

In a recorded video message Prime Minister Tony Blair said: 'We want to share our heritage, history and traditions. There is so much to experience. From our countryside to our culture. Our coast to our castles. And our theatres to our vibrant towns and cities. Here in Britain you can enjoy the traditional side by side with the most modern and contemporary.

'If you are coming from overseas, let us assure you of a very warm welcome. The UK is OK.'
