Singer Annie Lennox is supporting a campaign by UK charity Oxfam to sign up a million people in the fight against global poverty.
The former Eurythmics star has lent her voice to a TV commercial in which she invites people to phone, email or text in their support for the cause.
The Lennox advertisement aired on British TV network Channel 4 last night, and follows hot on the heels of the Make Poverty History campaign earlier in the year.
Oxfam's Judith Robertson says: "This has been an incredible year and shows us what we can do when people work together for change."
