Sri Lanka\'s inflation rate declined marginally in July to 6.1 percent from 6.8 percent in the previous month, latest data released from the Central Bank showed here on Thursday, but fresh tax increases are likely to push up consumer prices in August. The inflation rate on an annual average basis also decreased to 8.3 percent in July from 8.6 percent recorded in the previous month. However, Sri Lanka\'s government on Wednesday increased taxes on a range of items including cigarettes, alcohol, vehicle spare parts and dairy items, which is very likely to will push up inflation rates for August. Core inflation on both year-on-year and annual average basis continued to decline to 3.1 percent and 6.2 percent in July, respectively, from 4.3 percent and 6.4 percent, respectively, in June 2013.
