Sept 24 (Reuters) - Richard Holtum will take over as

Chief Executive of global trading house Trafigura from Jan. 1

next year, the company said on Tuesday.

Outgoing CEO Jeremy Weir will take up the role of group

chairman on the same date.

Holtum, who will become a member of Trafigura's board of

directors from October, will pass his role as global head of

gas, power and renewables to the current head of power trading,

Igor Marin.

Reuters exclusively reported in April that Weir had begun

priming Holtum to take the helm.
