To what extent is there a democratic deficit in the UK?

Intro: Define Democratic Deficit... then lay out your main points giving an indication to your conclusion

I would then go for 4 main over riding points

Mine would be

1. House of Lords

2. The voting system - FPTP (lib dems AV referendum it failed)

3. Parliaments ability to scrutinise itself un-codified constitution

4. The EU

5. Scotland, Wales and Northern Ireland don't have full independences

Assess each of these looking for an an argument of how much that contributes to a democratic deficit and then a point against that, before saying if it does create one.

Conclude overall

While we're here, should there be a mention of why we don't have a democratic deficit or is this just looking at the arguments that there is one...
