Slater and Gordon's (S&G) former UK chief executive Cath Evans has left the firm after returning to Australia earlier this year, it has emerged.

She moved back to Australia in March, in the midst of a restructuring of the firm's UK arm.

As part of the restructuring, S&G has closed offices in Halifax, Derby, Failsworth and Bristol, and "reorganised" its operations at Aston, Sheffield and Fareham.

A spokesperson for S&G said: "Cath Evans departed the UK in March this year to return home to Australia. After returning to Australia, Cath decided to leave the business, taking effect back on 30 June.

"During her more than 20 years at Slater and Gordon, Cath made a remarkable contribution and we know that she will continue to make her mark in whatever future endeavours she chooses."

Evans was CEO and COO of listed Australian firm S&G's UK business, coming to the UK following S&G's entry to the market through its acquisition of Russell Jones & Walker (RJW) in 2012.

Initially, she was head of the firm's UK general law/shared services division, before taking on the role of UK CEO – a role she held until summer 2015. In June last year, she became the CEO for group personal injury law, a role she held until she left the firm.

She joined S&G in 1994, rising through various management positions to take the role of general manager for corporate developments and operations for the Australia business between 2011 and 2012 – her last role before her move to the UK in 2012.

She returned to Australia in March in the context of a restructuring of S&G's UK businesses, which was triggered by massive losses connected with its acquisition of the professional services arm of Quindell in March 2015 for £637m. The firm wrote down £420m of the value of that business.

S&G's latest results, announced to the Australian Stock Exchange this week, show a net loss after tax of A$1.02bn (£587m) for the full financial year.

The firm lost A$958.3m (£553m) in the first half of the year and its expected loss after tax for the second half of the year is A$59.3m (£34m).

A spokesperson for the firm said: "We continue to progress with our performance improvement programme and the steps taken have indicated our efforts are beginning to bear fruit."

It also emerged last week that the firm's UK head of risk and compliance, Rebecca Bell, has left  to take up a similar position at Bates Wells Braithwaite.
