Global Oxfam ambassador Annie Lennox has vowed she is “not going to walk away” from the charity in the wake of the aid worker sex scandal.

Lennox, 63, has said she is “staying loyal to them” as Oxfam GB was temporarily suspended in Haiti pending an investigation into how the charity handled the case of former staff paying for sex.

The former Eurythmics singer supported Oxfam’s Haiti appeal at the time, and has praised their “extraordinary work” across the world.

“From what I’ve understood, Oxfam did their best to respond, but clearly what they did or didn’t do was terribly flawed,” she told The Sunday Times magazine.

“They’ve admitted that, and now they need to be absolutely rigorous.”

She said the charity is often “the first to be there” after a crisis.

however Lennox said her women’s network, the Circle would stop working with the charity if it does not improve.

She said:”It would be an absolute tragedy for millions of people across the world if Oxfam were no longer to function properly because their funding was cut.”
