According to this PDF London Road is still the A269: https://eastsussexgovuk.blob.core.windows.net/media/2462/bhlr_map_link_rd_and_a259_3a_3.pdf

Ah, thank you. Doesn't really clear things up, but I'll make sure to keep to the direction of the Wiki.

Mini roundabout direction in this country is "clockwise" by default, useless direction tag?
