The 2½ point lead that Manningtree A currently hold could be severely reduced in the next round of matches. Manningtree A face Bury St Edmunds B, not an easy match to win, whilst Ipswich C play Ipswich B. It's possible that by 4 April the two teams could be on level terms. However, Manningtree A's final match is against wooden spooners Ipswich B, so they probably hold a narrow advantage.
All will be revealed by 18 April, when the final matcvh is due to be played. But before then, Manningtree A, who play Ipswich B on 12 April, could have built up an unassailable lead.
