Bryon Lake, formerly the European head of Invesco's $11o billion Powershares business, has been bagged by JP Morgan Asset Management to boost its ETF business outside the US. 

Lake spent 12 years at Invesco, most recently as head of Invesco PowerShares in Europe, the Middle East and Africa. His departure was announced in February and chief operating officer Matthieu Grosclaude took over on an interim basis.
