Fellow Scot Niall Booker was recently appointed to run Co-op's troubled banking arm which is hoping to raise £1.5 billion to plug its balance sheet shortfall.
Mr Sutherland has had a baptism of fire since taking over in May. Days later the bank's debt was downgraded to junk by ratings agency Moody's and Co-op uncovered the huge hole in its balance sheet.
Half-year figures on Thursday are expected to show more deep losses triggered by impaired commercial property loans from its disastrous acquisition of the Britannia Building Society.
These sent the group plunging to a £673.7 million loss in 2012.
The Co-op is expected to slash the value of the bank to zero in coming months and could also reveal hundreds of job losses when it updates on the painful restructuring later in the autumn.
Its £1.5bn rescue needs the backing of investors through a "bail-in".
Bondholders ranging from pensioners to US vulture funds must accept losses on their investments if the deal is to progress.
The bail-in will raise £500m of capital by offering bondholders shares via an "exchange offer", resulting in a stock market listing for the group's banking arm.
But the turnaround has been complicated by US hedge funds seizing control of some of the bank's loans - giving them a strong bargaining position in the bail-in talks and potentially forcing even higher losses on lower-ranked retail bond investors.
The Co-op is also sharing the pain by selling its insurance businesses and raising new debt.
But it must also bolster its finances by slashing costs, with some of this expected to come from job losses among the bank's 10,000 staff.
Support services groups G4S and Serco are also likely to be under pressure as they reveal the impact of high-profile rows with the Government in first-half results.
The fallout from G4S's 2012 Olympics staffing failure - when military personnel were called in to fill gaps - was compounded when a new scandal emerged earlier this year around overcharging for electronically tagging offenders.
Auditors found both G4S and Serco overcharged the Government by "tens of millions of pounds" for more than a decade by billing for tagging offenders who were back in prison, had their tags removed, had left the country, had never been tagged in the first place or had died.
Both Serco and G4S then withdrew from the competition for a new tagging contract, which has since been handed to four other firms.
Analysts expect G4S, which reports on Wednesday, to post a dip in underlying annual profits to £408.7m this year, from £412m a year earlier.
Serco has told the City to expect strong revenue growth for the first six months, as previous contract wins filter through.
Investec expects Serco to report underlying full-year profits of £283.2m, up 4% on £271.6m in 2012.
Paving slabs specialist Marshalls reports half-year figures on Friday after sliding sales during a period hit by freezing weather.
The Huddersfield-based business revealed last month that revenues for the six months to the end of June were down 4% to £163m after trading suffered amid the coldest March in more than 100 years.
But analysts are optimistic about the future, with a forecast for full-year pre-tax profits of £12.7m.
Recruitment firm Hays announces full-year results on Thursday after a turnaround in the performance of its embattled UK division in the last quarter but overall profits are still likely to have fallen.
