Narrative:

While providing training at the athens and camebridge sectors (38/39); my trainee tried to get the business jet below an air carrier to facilitate his landing at bvy. The control instructions were not sufficient to maintain separation due to high tail winds and too small of a vector off course. The initial vectors were only 15 degrees and then an additional 10 degrees; these vectors were issued to both aircraft but not in a timely enough fashion. As separation was being lost; I asked the business jet to verify leaving flight level 260 but the transmission was blocked; I immediately requested the same information and received the report at which time business jet was told to resume his previous route. Recommendation; do not allow trainees to go as far beyond their limits as I did.
