MOSCOW (Sputnik) — The report surveyed over 600 companies working in sectors including transport, business services, computing and restaurants.
"July saw a dramatic deterioration in the economy, with business activity slumping at the fastest rate since the height of the global financial crisis in early-2009," Markit chief economist Chris Williamson was quoted as saying in the company's report.
According to the research group, output and new orders fell in manufacturing by 4.7 points and service sector by 6.8 points since June.
"At this level, the survey is signalling a 0.4% contraction of the economy in the third quarter, though much of course depends on whether we see a further deterioration in August or if July represents a shock-induced nadir," Williamson said.
On June 23, the United Kingdom held a referendum to determine whether or not the country should leave the European Union. According to the final results, 51.9 percent of voters, or 17.4 million people, decided to support Brexit, while about 16.1 million opposed it.
