It used to be available but Interactive Brokers (IB), which is Trading 212’s supplier no longer offers it on the LSE, so T212 is not able to offer it currently.
We might be able to get it in the future if T212 manages to access the other listing of Eurasia, in Stuttgart, but I don’t think that is on the immediate roadmap.
