The figures were revealed while Labour Deputy Leader, Harriet Harman, visited the city, attempting to defend Labour's waste on Sheffield City Council.
Local Liberal Democrat councillors are campaigning to save Sheffield's weekly bin collections, vital recycling services and local dementia homes, placed under threat of closure by Labour councillors.
Senior Sheffield Labour councillors have argued that no money is available but figures released today show a staggering £4.2m of wasteful spending.
In the last 12 months Labour councillors have:
In addition to this, Labour councillors turned down extra funds from the Government to help save Sheffield's weekly bin collections.
Commenting, Simon Hughes said:
"Labour needs to understand that elections are about priorities: protecting essential services and helping the most vulnerable. Whatever the financial circumstances, councils like Sheffield and others across the country run by Labour are making things worse by investing in the wrong priorities - spending millions refurbishing town hall meeting rooms whilst cutting dementia care.
"Liberal Democrats across the country are standing on a record of making the right calls for their communities in difficult times while Labour is trying desperately to turn attention away from their own records because they can't defend their terrible local record of slashing key services.
"No Liberal Democrat-controlled council in England is closing their libraries and some are opening new ones. Every Liberal Democrat council has frozen Council Tax and our councils have given the lowest paid workers a pay rise more frequently than Labour's. This comes on top of record rises in the state pension and giving nearly 25m basic-rate tax payers an Income Tax cut last year, this year and next year.
"Labour accepts the need to cut the deficit, but nationally have come forward with no credible plans for what they would do. Their record locally can only demonstrate what a disaster for our country another Labour government would have been.
"Instead of justifying plans to cut services unnecessarily, Harriet Harman should be asking her Labour colleagues what they are doing to tackle wasteful spending."
In March, Liberal Democrat councillors put forward a plan to save local services, which was signed off by independent council finance officers. Unfortunately, this plan was voted down by Labour councillors.
Labour-run Sheffield has approved a scheme to revamp meeting rooms in Sheffield Town Hall at a cost of £2.2 million - despite them having to make £55 million of cuts to services. This follows a £1.1 million refurbishment of the roof, wiring and lifts at the Grade I-listed building. http://bit.ly/JeoU2N
Liberal Democrats were planning a permanent £250 pay rise for the lowest paid council workers this year and next year. Labour cancelled this.
