The Ivy owner, billionaire Mike Ashley, and more Goldman bankers are being dragged into the BHS fiasco

A Green ally, Caring at one point owned 22.1% of BHS and was a beneficiary of the blockbuster £422 million dividend paid out by BHS in the early 2000s, according to The Guardian. Caring is a restaurant and clothing entrepreneur in his own right, best known as the owner of The Ivy in London's West End.

Alex Dellal and father Guy Dellal were involved in the property deals that helped fund the BHS takeover. Allied Commercial put up £35 million for Dominic Chappell, which he used to show BHS' then owner, Arcadia Group, he was serious. The £35 million was effectively a down payment for Marylebone House, a property Arcadia was selling separately, but that deal eventually fell through.

Henningson, a former advisor to Nordbank according to his LinkedIn profile, is a key ally of Chappell's who joined the board of Retail Acquisitions — the vehicle that bought BHS — after the deal completed. Henningson was one of the two directors that approved a £1.5 million payment from RAL to a company that owned Chappell's father's house. The other director was Chappell.

Lawyer Parladorio has already given evidence to the committee this week but has been recalled. Parladorio was on the board of RAL both before and after the BHS takeover. He excused himself from the vote on the £1.5 million payment — at the time he was the only other RAL board member.

A former bankrupt and convicted fraudster, Sutton first floated the idea of buying BHS to Chappell. Chappell helped Sutton work on the deal but Arcadia and Sir Philip refused to deal with Sutton and Chappell told MPs earlier this week that Arcadia CFO Paul Budge refused to even let Sutton into the Arcadia building. Chappell called Sutton "a grade-A scumbag."

Another returning witness, Gutman did unpaid advisory work on Chappell's bid for Sir Philip. Gutman previously told MPs: "We indicated to them that clearly the potential buyer here didn't have retail experience, clearly the proposal was highly preliminary and lacking in detail. We also indicated that the bidder here did have a history of bankruptcy."

Sherwood, nicknamed "Woody," is another key ally of Sir Philip. The pair became close during Sir Philip's failed attempted takeover of Marks & Spencer in the early 2000s, according to the Daily Mail.

It's not immediately clear what Casey's involvement in all this is but Goldman Sachs has repeatedly been described as the "gatekeeper" to Sir Philip by witnesses in this inquiry.

Khan is a long-time advisor to Sir Philip. Chappell claimed to MPs this week that it was Khan who recommended calling in administrators Duff & Phelps to BHS.

Titcomb is another recall. Her first session was attacked by Arcadia and Titcomb was later forced to clarify how she learned of the BHS sale in writing to the inquiry. Titcomb will likely be asked about her contact with Chappell prior to the sale, as Chappell claims he was blocked from contacting her by Sir Philip but received back channel assurances the regulator was amenable to pension rescue plans.

Budge, another recall, previously told MPs that the £35 million Chappell placed in an escrow account was a key factor in convincing him that Chappell was a credible buyer for BHS. Chappell told MPs this week Sir Philip knew this money was for the Marylebone House deal. This will likely be the focus of questioning.

Harris appeared alongside Budge and other Arcadia executives earlier this month but was a bit player. Wednesday's evidence outlined a spider's web of BHS property deals used to fund the business. MPs will want to probe Harris for more information.

Palos is Sir Philip's son-in-law, as well as being a director of the Green family's ultimate holding company Taveta. He bought the BHS Ealing store from the retailer for £6.9 million a day before it was sold to Chappell, a deal MPs will grill him on. The Daily Mail alleged Palos went on to make a £3 million profit from the transaction.

Lord Grabiner, a barrister by trade, chairs the board of Taveta Investments, the holding company that owns all of the Green family's investments. He has already appeared before MPs, answering questions about his oversight of the sale of BHS to Chappell.

Grabiner said he left an assigned team of other board members to carry out the deal as they were experienced people he felt he could trust.

Business, Innovation, and Skills Select Committee chair Iain Wright called Lord Grabiner's initial evidence "woeful" and said "effective corporate governance in BHS was almost entirely absent." Wright will want a better performance this time.

Chappell approached billionaire Ashley to buy BHS when it was clear he could not rescue it, he claims. Sir Philip Green "went absolutely insane" when he heard about the plan, Chappell claims, and blocked the bid. He then called in administrators. Ashley, who already confirmed his interest in BHS in his own Parliamentary inquiry, will only have to submit written evidence.

The above cast of characters are most of the key players in the BHS inquiry, however there are a huge number of bit-part players who have already given evidence. They are mostly lawyers, advisors, accountants, and consultants from bluechip firms like Linklaters, KPMG, PwC, and Olswang.

More niche financiers have also given evidence: Farallon Capital, RiverRock, and Cornhill Capital, who all help talks with Chappell over the deal. Pension trustees have also answered questions on their role in the whole thing.

A key witness who has not been recalled is Robin Saunders. A long-time Green ally and high-flying financier, Saunders has already told MPs that she was the one who introduced Paul Sutton to Sir Philip. That introduction set the wheels rolling on what eventually became Chappell's £1 takeover bid.

The most explosive testimony has been from former BHS management this week. CEO Darren Topp claimed £1 buyer Chappell threatened to kill him and alleged the former racing driver had "his fingers in the till," detailing payments made to Retail Acquisitions Ltd after the takeover. Michael Hitchcock, who was interim CFO at BHS at the time, called Chappell a "Premier League liar and a Sunday pub league retail... so many people believed him but he was a liar."

Chappell appeared at the same hearing, doing his best to defend himself by blaming Sir Philip Green and the Pensions Regulator for sending BHS under. MP Richard Fuller was skeptical, saying: "Isn't the truth of the matter that you don't take any responsibility yourself and just blame others?"

The 15 witnesses called by MPs will give evidence on Tuesday June 28 and Wednesday June 29.

Before that, we have a blockbuster session — Sir Philip Green himself. The billionaire Arcadia owner will answer MPs questions next Wednesday June 9, starting at 9.00 a.m. BST (4.00 a.m. ET). We'll have full live coverage on the day.
