And the answers are...
Once again, thanks to the dozens of you who responded to Simon's deer antler challenge in last night's show.
As revealed by Simon on tonight's programme, the results are, in clockwise order, roe, sika, red and fallow.
As many of you also pointed out, roe and red deer are native species, while fallow and sika were introduced here.
The other two British deer species found in a wild state, muntjac and Chinese water deer, were also introduced to Britain.
Some of you also pointed out that another species, Pere David's deer, can also be seen in some deer parks, while there is an introduced herd of reindeer in the Cairngorms.
Once again, many apologies for confusing you all with the reference to muntjac.
