Singer Melanie C and Barnardo's have teamed up with Duracell to launch its new #poweringsmiles campaign, which aims to provide the charity with toys and help fund therapeutic sensory rooms to create a safe and stimulating space for children with mental and physical disabilities.

Duracell will make a donation to Barnardos for every Like or Share of a Duracell UK Facebook post or any tweet using the hashtag #poweringsmiles. The former Spice Girl, who is the campaign ambassador, said 'I'm really pleased that through the Duracell Powering Smiles campaign we can all get involved in helping make Christmas special for more children'.
