Unity government = one party system?

I'll be honest, I don't get all this talk about a "unity government". Perhaps it's just a matter of perspective, but doesn't a democracy need to have an opposition? Wouldn't having one big party defeat the whole purpose? And how would it change anything? The CUD and UEDF would still have exactly the same percentage of people in government.

I'm no politician, but I think the CUD and UEDF need to just accept the result - flawed or not - and move on to the job of keeping the government accountable. They probably wouldn't be trying so hard if the next elections weren't five years away...
