The US parent company reduced its holding in the company to 51.7% at that time. In 1934, the 600th store was opened, in Wallington in Surrey. Expansion was effectively suspended between 1940 and 1950, owing to the Second World War and post-war restrictions, but then resumed. The 800th branch, at Wilton Road, Victoria, London, opened in September 1953. On 22 May 1958, the 1000th branch (known as "Portslade" to distinguish it from the existing Hove branch) opened in Boundary Road, Hove. The peak of 1,141 branches was reached in the late 1960s. From then until the US parent sold out in 1982, a number of branches were closed and sold, and at the time that ownership shifted to the UK, there were about 1,000 branches. Woolworths tried the large out-of-town store or hypermarket format in the 1960s with the Woolco stores. While some of these stores were closed, the majority were sold to the Dee Corporation in the early 1980s and re-opened as Gateway hypermarkets, later being taken over by Asda. One of Woolworths' flagship stores, on Briggate in Leeds, suffered a major fire in 1969. The store, which opened in 1913, was spread over four floors and sustained extensive damage, requiring a total refit. The store was not open to the public at the time and the building was evacuated, avoiding fatalities, although some staff suffered minor injuries. It took several hours for the fire to be fully extinguished. Split from owner and after In 1982, the British Woolworths was acquired by Paternoster Stores Ltd, the forerunner of Kingfisher plc. Woolworths Group plc was formed by the demerger of Kingfisher's general merchandise business, and began trading as a listed company on the London Stock Exchange on 28 August 2003, using the symbol WLW. In October 1984, the Woolworths stores in the Republic of Ireland were closed. In August 1996, market research was undertaken by Woolworths investigating opportunities to re-enter the Republic of Ireland market. About 32 potential locations were identified that could support a Woolworths store. However, the project did not proceed beyond the market research phase. During the 1980s, management rationalised merchandise lines into clearly defined categories: entertainment, home, children (toys and clothing) and confectionery. Many Woolworths branches were downsized during this time. Older branches in major cities were sometimes almost as large as the major department stores nearby. In 1987, for example, Woolworths left its five-floor branch
