UK's Johnson says Conservatives would raise payroll tax threshold

LONDON, Nov 20 (Reuters) - British Prime Minister Boris Johnson said on Wednesday that his Conservative Party would raise the threshold at which workers start to pay the National Insurance payroll tax to 12,000 pounds ($15,487) a year.

National Insurance is currently payable on earnings over 8,632 pounds a year, and the increase in the starting threshold would bring it in line with income tax.

"We're going to be cutting National Insurance up to 12,000," Johnson said in response to a question at a campaign event ahead of a general election on Dec. 12. ($1 = 0.7748 pounds) (Reporting by David Milliken; editing by Guy Faulconbridge)
