SINGAPORE- * Brent's premium to Dubai crude rises to $4.47 a barrel, highest since January 2016, Reuters data showed on Tuesday DUB-EFS-1M

* A widening of the price spread between the two markers supports demand for Dubai-linked grades from the Middle East and Russia while dampening buying appetite for Atlantic Basin crude priced of Brent

* Brent futures on Tuesday rose above $75 a barrel to its highest since November 2014, supported by OPEC-led production cuts, strong demand and the prospect of renewed U.S. sanctions on Iran O/R
