Sales of Sainsbury's Woodland eggs and chicken have paid for 300,000 trees to be planted this ­autumn.

Sainsbury's donates one pence per dozen Woodland eggs and two pence per Woodland chicken sold to the Woodland Trust. The funds will enable it to send out 10,000 "hedge & copse" packs, containing trees for schoolchildren to plant.

Sales of Sainsbury's Woodland products have raised over £800,000 for the trust. Last month, Sainsbury's said it was ­extending its Woodland brand to turkey.
