Michael Bruce, founder and chief executive of Purplebricks, is stepping down from the business with immediate effect.

Purplebricks is also quitting its Australian market and reviewing its US operations where it is looking at making cost efficiencies.

In the first hour of trading this morning, Purplebricks’ shares slipped by almost 6%.

Bruce will be replaced by Vic Darvey, who was previously chief operating officer, and joined Purplebricks only in January.

The statement released to the London Stock Exchange this morning said: “Whilst the UK property market remains challenging, the company continues to out-perform the market and the board remains confident about the future of the business. 

“Having established a market-leading position, there remain many opportunities for further profitable growth and this will be a key area of focus going forward.”

Purplebricks said that the prospective returns from Australia “are not sufficient to justify continue investment.” The business there will be run down with immediate effect, pending closure.

In the US, Purplebricks has materially cut investment in marketing and overheads, and begun a strategic review.

Today’s statement said: “As part of this review, management proposes to examine the options for delivering the next phase of growth in a more effective and cost-efficient way including more closely considering the opportunities and risks associated with a materially scaled back US business.

“A further announcement on this strategic review will be made in due course.”

Shares in Purplebricks have fallen by more than 60% over the past year.

Non-executive chairman of Purplebricks Paul Pindar admitted to mistakes.

He said: “With hindsight, our rate of geographic expansion was too rapid and as a result the quality of execution has suffered.

“We have also made sub-optimal decisions in allocating capital. We will learn from these errors and will not make them again.”

No announcement has been made about co-founder Kenny Bruce, who is understood to be in the UK helping oversee operations here.

However, this morning, Pindar paid tribute to Michael Bruce, saying: “I would like to place on record our thanks to Michael for the truly remarkable contribution that he has made to the creation and development of Purplebricks.

“Michael’s vision in creating the UK’s leading hybrid estate agent has been deeply impressive, as has his relentless energy in developing the business both in the UK and internationally.

“The board is delighted to have an executive of Vic Darvey’s calibre to take on the leadership of our business for its next important phase of development. We have a lot to do and Vic has a clear vision of the priorities we need to address.

 “Importantly, we are very conscious that the group’s performance has been disappointing over the last 12 months and we sincerely apologise to shareholders for that.”
