A third of children in London, some 600,000 youngsters, are living in poverty, according to a charity.
The End Child Poverty coalition said the figures for 2020-21 highlighted how many families cannot afford the essentials.
With the cost of living continuing to rise, parents are being urged not to attempt to hide financial difficulties from children.
The government said it was providing extra support for struggling families.
More than half of children growing up in Tower Hamlets were found to be living in poverty, while the figure was more than 40% in five other London boroughs – Barking and Dagenham, Greenwich, Hackney, Newham and Waltham Forest. That is compared to a national average of 27%.
