LKS 20160408 - LSN4928; A picture shows lambs in a pen at the farm of British farmer Toby Bulgin in Thetford, Norfolk, south east England, on March 22, 2016. As part of an EU sustainable agriculture drive, it subsidises Bulgin to flood some fields to create a habitat for wading birds, the money compensating for the loss of space in which to rear cattle. Bulgin fears that if Britain leaves the EU, it could deal a hammer blow to the nation's already-ailing agriculture sector. - TO GO WITH STORY BY ANTOINE BOUTHIER / AFP / LEON NEAL / TO GO WITH STORY BY ANTOINE BOUTHIER - LEHTIKUVA / AFP
