    Hi Caroline, In response to the original twitter discussion which you joined about people in the North-East giving most to overseas charity, we wanted to respons as follows:

    The article in question has been selective and is a bit misleading – the North-East at 59% did not emerge as the highest in our survey – Scotland did at 77%. But the article does rightly reflect the fact that our respondents’ answers did indicate the North-East generosity towards supporting overseas work has held up incredibly well despite the chilly economic climate.

    If you want to discuss more fully our tube ads, please do email as it is difficult to respond on twitter given the space limit.
    Best Wishes,
    Matt Whitticase
