One of the world's biggest consumer goods companies has predicted a "tougher" 2016 after reporting a slide in profits for 2015.

The company, which owns brands like Ben & Jerry's, Lynx, Marmite, Wall's, Domestos, PG Tips, Dove and many more, reported an 8% fall in pre-tax profits to €7.2 billion (£5.5bn).

Despite the fall in profits, underlying sales grew 4.1%. In emerging markets, where Unilever makes more than half its sales, underlying sales rose by 7.1%.

Paul Polman, Unilever chief executive, said: "We are preparing ourselves for tougher market conditions and high volatility in 2016, as world events in recent weeks have highlighted.

Despite having cut jobs and costs during 2015, Mr Polman said Unilever would continue its efforts to create a more "resilient" business.

"It is vital that we drive agility and cost discipline across our business," he added.
