Libya - Islamic Law

Late night thought:

The Telegraph reports that:

"Libya's interim leader outlined more radical plans to introduce Islamic law than expected as he declared the official liberation of the country."

"More radical than expected" - than expected by whom?
Certainly not unexpected by me,, nor by most bloggers that I read!

The Muslim Brotherhood

The BBC web site lists a number of bullet points about the Muslim Brotherhood, three of which are that it:

• Rejects use of violence and supports democratic principles
• Wants to create a state governed by Islamic law
• Slogan: "Islam is the Solution"

Can someone explain how the support of "democratic principles" can be reconciled with "a state governed by Islamic law"?
