Britain has cut the rate of interest on a loan of £3.26 billion made to the Republic of Ireland last year.
Eurozone ministers agreed on Thursday to reduce the rates that Ireland, Greece and Portugal pay on their European Union-led bail-outs.
The UK made the loan to Ireland late last year, at the same time as the EU and International Monetary Fund agreed to support the country.
Now the BBC reports the rate on the loan has been trimmed from 5.8% to 3.5%.
This is broadly in line with the reduction in interest Ireland will now have to pay for the EU funds.
