Former Conservative MP Lord Marland of Odstock has used the recent turbulence at the private client stockbroker to pour another £100,000 into the firm.
Marland - who was part of a consortium which invested £2.9 million into WH Ireland back in 2008 - has bought an additional 165,000 shares in the firm worth £94,000 based on its current share price of 57p.
The move lifts Marland's total stake in the firm to 1,769,359 shares, or 7.47%, worth a little more than £1 million.
The transaction comes shortly after WH Ireland appointed Richard Killingbeck as wealth head following the sudden departure of Paul Compton, who was understood to have left his post amid an investigation into his personal share dealings.
The upheavel sparked a slide in WH Ireland's share price, which at 57p sits well below its 12-month high of 102p.
