Can planners win clients from the private banks?

I would quite like to canvass some opinions on the following column I wrote for Investment Adviser this week, where I suggest some of the problems faced by private banks, might certainly at the edges, give financial planners the chance to make some inroads and win some clients from them. The column is on the FTAdviser website. Basically my suggestion is that some advisers must be moving up market not just by having larger minimums but by targeting bigger cases and wealthier clients at the top end. Certainly some private banks are making a hash of things. I would love to hear your views.
