Extra 20 Welsh Assembly Members 'could cost £9m more'

Increasing the number of AMs from 60 to 80 would cost up to £9m in the first year, according to a new report.

The Assembly Commission, which runs its day-to-day administration, suggests that moving to 100 AMs would add up to £17m to the current £50m budget.

The commission said it would be "a modest and reasonable price to pay" for effective scrutiny of £15bn of public spending every year.

The Welsh government has said there is "no appetite" for more politicians.
