Motorists heading north this weekend are being warned to expect long delays and tailbacks. Recent weekends have seen a flood of shoppers heading to towns in the North in search of lower prices. Thousands of cars were caught in traffic snarl-ups on the way into Newry yesterday as people ignored claims by the government that they were being unpatriotic by shopping in Northern Ireland. Bill Tosh from Dundalk Chamber of Commerce said shops there and in other southern border towns are fighting back and can offer value for consumers.
