Good cause of the day
A Winter Toy Appeal that collects gifts for thousands of children experiencing extreme poverty in north London urgently needs more donations. Last year the appeal reached more than 4,000 children, and the toys are distributed to children in most need via a network of social workers, hostels, refuges, a migrant centre, children’s centres, schools and food banks. The appeal only accepts new toys (for children aged 0-18), and the last day to donate this year is 7 December. Several businesses in Islington and Hackney act as drop-off points for new toys — full list here.
