So much for 'tightening belts' then.
I would imagine that there are many employees of the council who will be interested to learn of this.
Update 15th July;
I have now been informed that this £20,000 is for Returning officer fees, for 2011/12. This will have included the Welsh Assembly ( plus Alternative Vote referendum) elections held in May 2011. The RO fees for the local elections held in May 2012 and the Police Commissioner elections later this year will appear on 2012/13 Statement of Accounts senior salary.
As far as I can make out, the maximum personal fees for Returning Officer services for the Assembly and AV Referendum in May last year was £4,730 (see here) I assume the figure of £20,000 classed within 'Salary' includes additional unspecified expenses and covers fees for more than one constituency.
If this is the case, I am of course happy to clarify the situation.
Should the returning officer retire during an election year, the fees would also be included towards the final salary pension.
Update 2013 - Plaid Cymru politicians have made further investigations
