FIA confirm concrete frame on manhole cover is the issue
As we mentioned earlier, the FIA have now confirmed is the framing around the manhole cover.
They have said: "Following inspection, it was the concrete frame around a manhole cover that has failed. We now need to check all of the other manhole covers which will take some time.
"We will be discussing with the local circuit engineering team about the length of time it will take to resolve and will update with any resultant changes to the schedule."
