UBS is looking to boost its wealth management business presence in the US as it continues to jettison the legacy of Credit Suisse, including by selling a corporate jet used by the scandal-hit bank's former chair, according to reports.

UBS wealth management head Iqbal Khan told Swiss newspaper NZZ Am Sonntag that US growth would play a key part in its bid to reach annual net inflows of $150bn a year, with "heavy" investment planned over the coming three years.
