Call your local council and ask them to clarify if you are registered to vote.

On the 19th of September 2014 a new system was introduced in the processing of applications to be added to the voters roll in Scotland.

I believe the DWP ( Department of Work and Pensions UK ) now carefully look at applications and grade them with either Green, Amber or Red. This can prevent you from being registered. If you are considered either Amber or Red you might be taken off the register.

I think it very wise that every single voter in Scotland check that they are registered to vote. In Glasgow right now you cant get clarity on the phone as their system is down and has been for 5 days. 

The cut off for online applications in Glasgow according to a person at Glasgow City Council (no doubt situated in the Kremlin on George Square or close to it) is the 17th of April 2015 and postal applications is the 7th of April 2015. 

Local authorities across Scotland will have their own times. Clearly this new system will effect the numbers able to vote. My advice is not to re-register online. Call your local council and ask them to clarify if you are registered to vote. 

Many may be left very disappointed if the new changes are not widely acknowledged.
