Almost 80,000 members of Leeds Building Society voted at the annual general meeting, re-electing, Robin Litten, Kim Rebecchi and Les Platts, as well as electing Susan Cooklin to the board as a new non-executive director.
Robin Ashton, chairman of Leeds Building Society, said: “I’m delighted by members’ support for the Board following Leeds Building Society’s strong performance in 2013, which clearly demonstrates the continued effectiveness of our business model and the important role building societies have in UK financial services.
“Each director received more than 95% votes in their favour, which I believe endorses the Society’s strategy for running a successful business and continuing to invest in sustainable growth to deliver security, value and excellent service to members.”
Leeds recorded its best ever net residential lending figure of £992m.
