UBS has won the first battle in a legal dispute against Vestra, the start-up wealth manager headed by the Swiss bank's former top private banker in the UK, David Scott, and four of its senior employees.

The High Court judge has this morning ruled that UBS should be entitled to a springboard injunction on the grounds that Vestra deliberately solicited clients and staff away from UBS, and that senior ex-UBS staff breached their duty of fidelity.
