Cille in the unipotent radical of a k-parabolic subgroup of G if and only if each element is k,-embeddable in a Bore1 subgroup. Using moreover Corollary 3.3 of [13], we are reduced to the following case: k = k,, U is generated by an element u of order p, G/k is split and almost simple, G has not type C,. Let us set K = k((t)) and denote by Kmod a maximal tamely ramified closure of K.
