The RSPB has defended a decision to cull 250 red deer on a nature reserve in Suffolk.
The conservation charity, based in Bedfordshire, has been criticised for killing the animals at Minsmere, on the coast near Southwold.
t says the cull was necessary because a significant increase in deer numbers was having a negative impact on other wildlife. The RSPB said the animals had no natural predators.
