By Suban AbdullaLONDON (Reuters) -Britain’s labour market is showing more signs of cooling and businesses remain negative about their prospects in the coming months, according to surveys published on Monday. Job search website Adzuna said online job adverts fell by 1.3% in the 12 months to August – the first such drop since February – and by 2.1% in month-on-month terms. However, vacancies remained higher than in January, typically a peak hiring month, which suggested the jobs market is “cooling, not collapsing,” Adzuna said. Official data published earlier this month showed vacancies rose in the three months to August and wage growth cooled slightly in the May-to-July period. The CBI said expectations measures in its surveys of manufacturers, retailers and other services industries fell to -20 for the three months to December.
