Stupid road markings

this one confuses me every time, a T junction, but for some reason only cyclists AREN'T allowed to turn right....? I have no idea why..... it doesn't turn on to a dual carriageway or motorway just another regular road....

you might have to move about a bit streetview to see it heading the right way, a car is covering the sign when you are looking towards the junction

No, the road markings are correct. It might be clearer if they were in the nearside lane, too, but that might lead cyclists to position themselves incorrectly to go straight ahead through the modal filter (the cycle gap). As it is, what is meant is that cyclists should position themselves in the offside lane to go straight on. It does not mean a prohibition against turning right. (If the markings were in the nearside lane, as well, cyclists might get wiped out more easily by left-turning cars.) I haven't checked all the details of signage etc. (there are usually mistakes made at complex junction arrangements), but I don't see a problem here.
