Our Local Councillor in San Fulgencio,wrote on his blog less than a week ago,Regarding the Padron and he stated,that if your Padron is more than TWO years old,Central Government will strike out your details and your Council. Will not get any help from them cash wise for the things they help with at the moment.
In the case of my local council, this is probably a good thing. Less money for them to waste. We have 600 employees "working" at the town hall. Total population is around 11,000, so one town hall "worker" for every 18 people.
