After five years of failed tenders and political turmoil, Latvia is once again bringing Latvian Shipping to the block in the hope of finally selling the company that has unseated governments and marred the country's image. Investors looking at the potential privatization of the 68 percent stake the state is offering in the world's 19th-largest shipping firm in tonnage terms, have until 10:00 GMT on February 1 to express interest in taking part in the company's fourth sell-off tender. A final auction is expected in May. As with previous attempts to privatize the company, the latest effort has been surrounded by political bickering. Despite the dismal backdrop for the sale, however, the government says this time it is convinced it will succeed.
