Unilever shares rise as billionaire investor Nelson Peltz joins board

Hedge fund boss - whose daughter married Brooklyn Beckham - holds 1.5% stake in Unilever

Unilever's share price has risen after the consumer goods company announced that the billionaire activist investor Nelson Peltz is to become a board member.

Peltz, the US founder and chief executive of Trian Fund Management, has been building his Unilever stake since January amid growing speculation that he will push the Dove soap and Marmite manufacturer to shake up its sprawling operations, with the company under increasing pressure to sell off brands or consider a break-up.
