Scotland is always pleased to grant independence to nations within Iberia when the time is right. We have rarely denied such a request so long as the people of the territory agree to one binding clause that all nations in Iberia (excluding Valencia) are bound to: should their land ever destabilise into anarchy the territory shall immediately be confiscated and returned to Scotland.
As Scotland is a member of the Iberian Pact, we have deemed fit to naturally allow former Iberian Pact members that descend into anarchy to become a protectorate of the Iberian Pact. You are correct in stating that the Kingdom of Spain never signed the Iberian Pact, and therefore this land is officially a protectorate of Scotland. You will step down and allow Scottish government to retake control of this land or we will enact our right to do so. We will defend this territory from unwanted usurpers to the throne.
OOC: Once again, you need to stop 'declaring independence' in my land when it does not belong to you. If you back off for a while we can re-discuss this in a few weeks, and maybe I will re-consider. In the meantime you have offended my nation IC so you are denied.
