British politicians will visit Dublin this week to investigate the success of the smoking ban.
The all-party parliamentary group on smoking and health will talk to their Irish counterparts about the law, which was introduced six months ago, and see what lessons could be applied to the UK.
As well as meeting members of the anti-smoking lobby, the politicians will meet former minister for Health, Micheál Martin.
David Taylor, chairman of the group, said: "The smoke-free law in Ireland is clearly popular and is already bringing health benefits due to the fall in smoking. Our delegation will be meeting the people who helped to bring about this landmark legislation."
Research in Ireland has shown overwhelming support for the ban, with compliance running at around 97 per cent.
The group will arrive in Dublin on Wednesday evening before talks on Thursday.
The visit comes ahead of Britain's public health White Paper, due to be published next month after a lengthy consultation process.
British Health Secretary John Reid has already signalled that the status quo on smoking cannot continue, but he is expected to stop short of ordering a total ban on smoking in all workplaces, including pubs and restaurants.
