The number of job vacancies in the UK increased last month at the slowest rate in almost a year, according to a survey by the Recruitment and Employment Confederation (REC).

The number of people appointed to permanent jobs in September also grew by its slowest pace in 12 months.

"The report shows that the jobs market is starting to flatline and may herald a 'double dip' in employment," said Kevin Green, chief executive of the REC.

"While there is growth, these figures are the worst we have seen for a year. The government must do everything possible to avert the threat of increasing unemployment."
