Well I've got to be honest, I'm genuinely gobsmacked.
Maybe the sudden surge of socialism and lurch to the left wasn't to be unexpected in light of years of economic pain and austerity.
But I think Cameron must have thought he'd won the lottery when Corbyn won. Labour now needs to rewrite recent history, dismantle it's current image and rebuild itself as a true socialist and trade union party, something I never thought I'd see again in my lifetime.
It will be interesting to see if Corbyn policies can be tempered by Labour moderates, such as bringing back nationalisation and scrapping Nuclear weapons, or if this really is the new style Labour party.
Business leaders seem to be cautious in their responses as they wait to see how the Corbyn led party shapes up, and how his previous Tax business approach pans out.
What do people think?
Do you think Corbyns Labour will be a boost for small businesses or a danger? As Rebecca says, it looks like we will have some lively exchanges to look forward to
