Sources suggest the banks were wary of the firm鈥檚 optimistic figures

好色先生TV this week that the collapsed social housing firm had a 拢42m black hole in its accounts has been followed by further revelations about why the banks rejected its three-year rescue plan.

好色先生TV revealed last week that the plan required the RBS-led group of lenders to inject 拢50m within a month to keep the company afloat.

好色先生TV understands the plan was based on the assumption Connaught would make a profit of 拢17m on turnover of about 拢450m by year three. One source close to the administration process said: 鈥淭he banks realised those figures were optimistic. Another major flaw in the plan was that the Connaught name was already damaged.鈥

Morgan Sindall鈥檚 Lovell arm is providing emergency repair work on the 拢17.5m deal Connaught started with Norwich council in April after a legal challenge by losing bidder Morrison, which alleged Connaught鈥檚 bid was 鈥渁bnormally low鈥. According to both sources, the job will make a 拢2m loss this year.

Although Morgan Sindall took on the bulk of Connaught鈥檚 contracts, 好色先生TV understands some councils may make alternative arrangements. One source said: 鈥淚 think Morgan Sindall will still see it as a good deal if only 50% of the contracts went across to it, if they were the more valuable ones. It did its homework on this deal.鈥

Question marks have been raised by some over the fact Morgan Sindall paid out 拢28m after a relatively short period of due diligence. One losing bidder said: 鈥淕iven all the extra money Morgan Sindall will have to throw at the company, I do wonder how it will make this deal pay any time soon.鈥

Morgan Sindall declined to comment.

Meanwhile a series of probes could be launched into the collapse. Connaught faces a business department investigation if evidence is found of wrongdoing. The Actuarial and Accountancy Discipline Board will decide 鈥渨ithin weeks鈥 whether to probe auditors Pricewaterhouse Coopers. Meanwhile, it has emerged that the Financial Reporting Review Panel asked Connaught鈥檚 directors to clarify its accounts after a profit warning on 25 June.
