June 3 (Reuters) - Britain's FTSE 100 index is

seen opening higher on Tuesday, with futures up 0.09%.

Keysight Technologies ( KEYS ) to divest three of Spirent

Communications' ( SPNUF ) businesses to resolve antitrust concerns

its approach to defence to address threats from Russia, nuclear

supply, with Iran set to reject a U.S. nuclear deal proposal,

while weakness in the dollar also supported prices.
