The poorest parts of the country will suffer most from the Government's tax credit cuts, according to a new study.
The TUC says average losses are calculated for a year from next April when the cuts are due to come into force.
It says in Wales the loss will be just under £1,400. The biggest impact will be in Northern Ireland, where the average loss to claimants will be £1,480. Average losses in London will be £1,110.
