A position at the heart of a resurgence in London IPOs has helped UK stockbroker Numis Securities more than quintuple its full-year, pre-tax profits.

Numis, run by chief executive Oliver Hemsley, this morning reported its full-year results for the year to September 30, a period during which pre-tax profits soared by 445% to £22.6 million on a statutory basis. Revenues, at £77.7 million, were up 55% year-on-year.
