Its generous contribution means there is now an impressive £235,000 in the fund, says the NFRN.
The NFRN created the Hardship Fund to help members who are facing severe hardship as a result of the coronavirus pandemic.
Since its launch in April, the Hardship Fund has helped nearly 70 independent retailers and paid out £100,000.
A small team of officials, led by NFRN Vice President Muntazir Dipoti, have been mobilised to assess all applications.
The Federation says it will provide help quickly to the applicants that need it most.
News UK Chief Operating Officer David Dinsmore said: "News UK is incredibly grateful for all the work of our retailers throughout this pandemic to keep newspapers on the shelves, and in many cases starting or strengthening home news delivery services, ensuring nobody misses out on their favourite newspaper. We are proud to be supporting the NFRN’s hardship fund for hardworking retailers who have fallen on hard times and will continue to work with retailers to ensure we continue to serve our readers and your communities.”
NFRN’s National President Stuart Reddish said: “I am so pleased that News UK has decided to back our Covid-19 Hardship Fund.
“Independent retailers need our help now more than ever, and it’s great to see that so many companies have come together to support them."
