It's easy enough to keep both business and the unions on side when you are vague about your policies – and when your opponent is messing up so badly. That was Labour's position going into the election. But now that it's in government, can it keep that balancing act up? Next week's Labour party conference will be the government's first real test. James Heale talks to Kate Andrews and Paul Nowak, general secretary of the Trades Union Congress. Produced by Cindy Yu.
