Well so far he has:
- Banned consumption of alcohol on the tube, DLR and franchised London bus routes (frankly I'd have left this to the operators, but it is neither here not there);
- Appointed a Forensic Audit Panel to investigate financial management at the GLA, with an interim report on how to make savings within 30 days, with a full report within 3 months of areas of spending cuts;
- Withdrawn an appeal by the Mayor to the High Court against Thames Water developing a desalinisation plant powered by renewable energy (to provide auxiliary water supply for London). Ken Livingstone opposed it because he saw the plant as a "waste of energy";
- The Mayor's newspaper/propaganda sheet "The Londoner" is to close, saving £3m p.a...
So within a month there may be more savings, and after 3 months hopefully a plan for more. However I'd like to see a few more zeros behind the savings than just 6.
