I was approacing a roundabout indicating to turn right and proceeded to move into the right lane and then onto the roundabout after checking it was clear to my right. To my left, a van had stopped giving way to me, however once on the roundabout, another road user has came onto the roundabout from the vans near side without giving way, hitting my front near side. The insurance compay is trying to say its split liability, even though i was already correctly on the roundabout and she failed to give way
