TV presenter Louise Redknapp has teamed up with Actimel to star in its winter campaign, promoting ways to stay positive during the cold months by tackling wind and fake snow in a giant snowglobe, as part of the brand's challenge to 'lift the lid off winter'.

Redknapp is encouraging the public to take part in the challenge at King's Cross station today and tomorrow (February 15 and 16), to be in with the chance of winning a MINI Cooper, and she commented 'It's been really fun working with Actimel and thinking about how I stay resilient myself.... Staying strong mentally and having a positive attitude is so important, even if it is raining and snowing outside and it’s so cold you don't want to get out of bed'.
