The government will clamp down on tobacco smuggling, it emerged in this week's Budget.
The Chancellor said cigarette companies would be fined heavily if they did not take steps to prevent their lines being smuggled into the UK.
He also outlined measures for tobacco producers to monitor their supply chains to restrict access to smugglers.
Brown said duty on cigarettes would rise by nine pence, which has already invoked an angry response from shopkeepers. Ken Patel, the national spokesman for Retailers Against Smuggling, said: "With this tax rise, Gordon Brown has just created greater opportunities for smugglers."
Pressure group Action on Smoking and Health said it welcomed measures to fine suppliers for smuggling.
