No white lines to separate traffic

Basically on this stretch of the road for the last year of 2022 the lines are non-existent and traffic joining the Dereham using the small sliproad (see pics) are having a hard time keeping left and more then often they end up driving in the middle of Left & Right lane posing a danger for people who are already in the Left & Right lane that are already on the road.Also it's even more dangerous when its raining and drivers have no idea how to position themselves.The picture uploaded show how bad it is and is getting worse as people also ignore that is a Giveaway and force existing traffic to slow abruptly or to change lane.
