This completes the draw for this season's British & Irish Cup campaign so Wales' clubs now know who they will be up against in the competition if they win their Regional play-off final.
The draw was made at a meeting of the WRU and Premiership clubs, and places the winner of the Gwent play-offs in Pool 1 with Ealing, champions Leinster and Mosely, the winner of the Blues play-off between Cardiff and Pontypridd in Pool 2 with competition newcomers Edinburgh Academicals, along with London Welsh who return after a year in the Premiership and London Scottish.
The winner of the Scarlets play-offs will play Bedford, Rotherham and Connacht in Pool 3 and the winner of the Ospreys play-offs will meet Leeds, Bristol and Gala in Pool 4. The British & Irish Cup proper kicks off in October.
Final positions in last season's Principality Premiership determines the number of matches teams play, and will give teams home advantage.
