Put simply, there aren't as many of these as we'd like or as would be appropriate to the level of support that the party has in Scotland.
However, if you're concerned about some matter that's dealt with at Westminster rather than Holyrood or Glenrothes, then there are Conservatives in place to help you.
On these, as on all subjects, you can simply contact DECA. This is the right course of action for issues centred on Fife, since we know the local terrain.
If you want to raise something more general, you could contact Peter Duncan, MP, the Shadow Secretary of State for Scotland.
