At Virgin Money, where Tugwell has been since 1986, he worked as southern divisional manager before becoming director of intermediary relationships.
He has served on IMLA’s management committee since 2012.
Tugwell said: “I am honoured to be asked to serve IMLA as deputy chairman and will strive to represent the membership and the industry fully in this capacity.
“The mortgage market is undoubtedly undergoing a number of fundamental changes over the next few months, and I am excited by the prospect of working alongside the executive team to usher IMLA and its members into this new chapter.”
Paul Darwin has been head of intermediary sales at Skipton intermediaries for 10 years, while he was previously national account manager and area manager.
He said: “I am delighted to become part of the IMLA executive team in these exciting and changing times.
“Alongside greater optimism in the housing market and a strong uplift in mortgage growth, there are new challenges in the form of more stringent regulation and an increasing percentage of business through the broker channel.
“I am looking forward to working with the existing IMLA management team to contribute my own knowledge and experience, to help shape and sustainable mortgage market for the long term”.
Darwin started as a Nationwide graduate trainee before joining Norwich and Peterborough as a district manager.
The two new faces follow the appointment of Charles Haresnape, managing director for residential mortgages at Aldermore Bank, who will serve as IMLA’s new chairman until its annual general meeting in November.
