But from what a few news outlets reported I interpreted it as Marcus did bring some backing which may have held implications in him retaining his seat over other candidates such as Antonio Giovinazzi.
This will be a long post, and it might be a bit messy at points, but the whole Sauber-Ericsson situation is clouded in secrets, anonymous people and slightly weird decisions - but it is quite interesting.
That is one way to put it. His backers have never
really come public and said they are backing them, and it doesn't look like Swedish media are doing much investigative journalism around it either. However, others have. Through his Jr.Formula years, it was talked about that his private, secret backers were the Rausing-Family and Persson-Family (Tetra Pak and Hennes & Mauritz (H&M)), this was never confirmed.
When Longbow-Finance bought Sauber it was billed as a Swiss investement firm - and strictly speaking, it is,- as it is a Swiss firm, and investment. And while they don't have to file public records on who is behind it. However, one of the former names of Longbow-Finance was Tetral Investement Management SA, and the company have the same address as Tetra Laval International SA, the parent company of Tetra Pak. You can see how the connection goes a full circle there.
In addition. Marcus Ericssons manager, is Eje Elgh (The Swedish expert commentator). When Eje Elgh had a STCC team, one of the drivers were Calle Rosenblad, Rosenblad is the grandson of Holger Craaford, who was one of the initial founders of Tetra Pak, together with e.g the Rausing-family.
To further bring in Swedish racing personalities, before Eje Elgh took the role as Ericsson's manager, he had Kenny Bräck as manager (the former CART/Indy driver) was also connected to Longbow, at least until he stopped working with Ericsson.
Now, this can be just adding 2 and 2 and getting 8, because it looks like most logic. Unless you turn back time to before Ericssons time in F1.
Up until 2010, Marcus Ericsson owned 60% of a UK company under the name "M E Promotions Limited" The remaining 40% was owned by a UK business called
Sportpro, which listed "activites in sports sponsorshop" as description. Sportpro was in turn part-owned by Swedish
Ramsbury Invest. This is the private real estate of
Stefan Persson who is the chairman of H&M, and the 17th richest person in the world. His son
Karl-Johan Persson is also a shareholder in Ramsbury.
On the board of M E Promotions Limited was Marcus Ericsson, His father Thomas and a certain Karl-Johan Persson.
M E Promotions was dissolved in 2010, however a company with the same name still exists, now in the Netherlands, and Sportpro still owns 40% of that company. (Don't know the reason for this - but I guess there is something about taxes, secrecy etc. that makes it wiser to have in the Netherlands compared to the UK).
The biggest shareholder in Sportpro by a "strange coincidence" is Longbow-Finance, just to tie up the connections even more.
In addition to this, shareholders of Sportpro includes the mentioned Kenny Bräck, but alongside Longbow and Ramsbury is also Olsbergs, a fairly large electro-hydraulic control system manufacturer in Sweden.
To finish it all off, Pascal Picci was appointed as the new Chairman of Sauber when Longbow bought the team. Picci is on the board of Sportpro, together with Karl-Johan Persson and Finn Rausing of the Rausing-Family and Tetra-Pak/Tetra Laval.
So, while they are trying to not talk about it in Sweden by the looks of it, and there is no interest in finding out who is pouring out so much money to found Swedes in F1/F2 it seems pretty likely that the same people who have bankrolled the whole career of Ericsson, also are the people that owns Sauber. And thus, Ericsson should be pretty safe for a Sauber seat for as long as they like each other.
On a personal note is why this leaves a slightly bad taste in my mouth. One is the complete secrecy, and the way people connected to longbow,sportpro,tetra,Ericsson etc. also works for the Swedish F1 broadcaster, and seemingly tries to undermine the connections. It is also the drivers that seemingly gets backing.
While you had some of the same in Mexico, with Telmex deciding to found drivers to get a Mexican in F1, and they chose Perez and Gutierrez. At least there have been no secrecy, and it was about finding the
best driver from Mexico to put in the seat.
Here you have Ericsson being backed, and then seemingly out of nothing Sauber decided to give Gustav Malja test in the in-season test. Just to show that they support Swedes that are somewhat sub-par. Malja have 5 podiums in 3 seasons of F.Renault 3.5 and GP/F2. and a total of 5 race wins in 7 years of single seater racing. While that happens you have Felix Rosenqvist driving whatever he is able to due to little money and winning in almost whatever he drivers, no matter if it is F3, FE, GT or Indy Lights or the BMW Junior Joel Eriksson.
Oh well. Long post, and I guess many jumps out halfway. Regardless TL;DR - Ericssons backers and owners of Sauber are the same. Ericsson is safe unless Sauber is effectively bought by someone else.
