Colin Fitzgerald, who stepped down almost a year ago to the day as head of institutional business at $275 billion asset manager Fidelity Worldwide Investment, has returned to the industry as head of Invesco's institutional business in Europe, the Middle East and Africa.

Fitzgerald had run Fidelity Worldwide's institutional business for just five months from November 2013 until March last year, when it was confirmed he was leaving for "fresh challenges" after the completion of the merger of the marketing divisions of Fidelity Worldwide and sister company Pyramis Global Advisors.
