To undercharge, and even worse to renegotiate existing contracts, would leave the sport's new owners in a difficult spot and could lead to every race organiser insisting their fees to reduced.
If not Silverstone, then where?
With Liberty Media and FOM looking to increase the number of races on the calendar, it's clear from the Silverstone deal that they'd rather create new events in destination cities rather than renegotiate ones that aren't working.
Having indicated that they'd prefer more street circuits, London becomes the obvious substitute for a British Grand Prix. This comes with it's own challenges, but if Formula E can do it, why not F1?
Alternate locations in the UK include former GP circuit Brands Hatch which shared the British Grand Prix with Silverstone in alternating years through the 60s, 70s and into the 80s before Silverstone became the permanent home of the race in 1987. It seems though that they are not equipped, nor can they afford to host an F1 race either.
Whatever the outcome, Liberty Media certainly want a race in Britain to maintain their core fanbase. Although the BRDC are desperate for the race to continue at Silverstone, they can't continue if the costs lead them to ruin.
Will FOM take control of the British GP themselves?
Short-term relief could come from FOM directly, with an offer on the table to take over running of the race at Silverstone for five years to keep it running while a solution is found.
