If it is literally just relative risk you are interested in (not judging, just saying!), then this might be of use -

Basically repeat ELCS is SAFER for the baby than a VBAC. Check out the view on RCOG, too - even they admit it, and they tend to be very pro-VBAC.
As others have said, risk is a complex picture. If you wanted lots of kids, then some risks are increased with repeated CS which aren't great (placenta accreta for example, and scar adhesions).
if you want to take a wider public health view, than VBACS are cheaper, given the way the NHS currently accounts for birth, even though something like between 1 in 3 or 1 in 4 (depends on hospital) end up as EMCS. This is one reason why the NHS push them. Especially as women may end up having more than 1 or 2 DCs. I'm not suggesting you should take this into account, btw - just that when you tell women that VBAC carries a proportionally greater risk (though still VERY small) of the baby being born injured or stillborn than a repeat CS does, then the next question they ask is why the NHS are pushing VBACS.
Remember that the part of the NHS that pays for birth and midwifery does not pay for aftercare of mothers damaged in birth, physically or mentally, nor does it pay for the care of infants damaged during birth.
Another thing to bear in mind with a view to CS or VBAC is your health - if you are very overweight, have blood pressure/blood clotting issues or any allergies to painkillers or antibiotics, this will increase the risk to you of an ELCS.
I wish you all the best. It is not an easy decision, I understand.
