Dettol and Lemsip maker Reckitt Benckiser will be launching a raft of new products into the UK this year under the Vanish, Calgonit, Veet and Airwick brands.

Reckitt posted a 9% rise in pre-tax profit to £545m on sales up 3% to 3.5bn. But shares nosedived as descendents of the founding Benckiser family revealed they planned to slash their stake in the company.
