Who will get booted from the Wells Fargo wagon?

The embattled bank’s board faces a showdown with shareholders on Tuesday morning as the fallout from last year’s fake-accounts settlement continues to plague directors.

On one side of the battle is Warren Buffett, with about 10 percent of shares. He has already voted and is likely to have supported the board, Reuters reported last week.

On the other is proxy adviser Institutional Shareholder Services, which recommended investors fire 12 of Wells’ 15 directors.

Some shareholders, including pension funds for public employees in New York, California and North Carolina, have signaled that they are going to vote against at least some of the bank’s directors.

While large investors are going to make their own independent decisions, proxy advisers like ISS are “a heavy influence on at least half of the top 10 investors,” Bruce Goldfarb, CEO of Okapi Partners, told The Post.
