Where now for Zambia?

The people of Zambia will go to the polls in the New Year to elect a successor to former President Michael Sata. The BBC's Lucy Burton reports from the copper-rich country and hears from those who don't feel they've shared in Zambia's growing wealth. She also speaks to Zambian finance minister Alexander Chikwanda. Also as the US Senate prepares to vote on whether to approve the final stretch of the Keystone XL pipeline, we hear from one end of it - the Canadian province of Alberta, whose tar sands provide huge quantities of oil at what many argue is an unacceptably high environmental cost.
