Does the dual Banach space $B(\ell^\infty)$ has weak* normal structure?

Let $K$ be a bounded closed convex subset of a Banach space $E$. A point $x$ in $K$ is called a diametral point if $$\sup_{y\in K} ||x-y||=diam(K).$$ where $diam(K)$ denotes the diameter of $K$. The set $K$ is said to have normal structure if every nontrivial (i.e contains at least two points) convex subset $H$ of $K$ contains a non-diametral point of $H$.

A dual Banach space $E$ has weak* normal structure if every nontrivial weak* compact convex subset of $E$ has normal structure.

Does the dual space $B(\ell^\infty)$ of bounded linear operators on $\ell^\infty$ has weak* normal structure?

Recall that the natural predual of $B(\ell^\infty)$ is the space $\ell^\infty\hat{\otimes}\ell^1$ where $\hat{\otimes}$ denotes the projective tensor product.

Could you give an example of a dual Banach space which does not have weakstar normal structure? –  Yemon Choi Nov 13 '10 at 18:18
The set $\lbrace (x_n): \sum_n x_n=1, x_n\ge 0\rbrace$ in $\ell^1$, as a dual of $c$, is such an example. –  TCL Nov 21 '10 at 12:57
