A year ago this week, as Neil Woodford’s new fund opened to investors, there were two big questions: could he replicate the success of his 26-year tenure at Invesco Perpetual, and could his successor, Mark Barnett, step out from his shadow?

Woodford's new equity income fund opened to investors last June, while over at Invesco, Mark Barnett was only just getting comfortable, having assumed responsibility for his predecessor's funds two months earlier.
