According to the Bible, none... All 12 partook of the emblems. Jesus told them to partake even thought they were not anointed with Holy Spirit yet.
This came like a flash of light (not in WT sense) to me. Indeed, the apostles were anointed at the Pentecost. Yet they partook. Hence, it's clear that anointing is not the sole basis for partaking in the Lord's evening meal. Furthermore, look at John 6: 48-51, then 54-56 and see the words in bold.
48 I am the bread of life. 49 Your ancestors ate the manna in the wilderness, yet they died. 50 But here is the bread that comes down from heaven, which anyone may eat and not die. 51 I am the living bread that came down from heaven. Whoever eats this bread will live forever. This bread is my flesh, which I will give for the life of the world.”
Whoever eats my flesh and drinks my blood has eternal life, and I will raise them up at the last day. 55 For my flesh is real food and my blood is real drink. 56 Whoever eats my flesh and drinks my blood remains in me, and I in them. 57 Just as the living Father sent me and I live because of the Father, so the one who feeds on me will live because of me.
The words "whoever and which anyone" do not limit partakers to one group, e.g. anointed class. I wonder why the Governing Body is preventing majority of JW community from partaking.
