The Sun is recruiting 16 new journalists to work exclusively on its Sunday edition.
The Sun Sunday was launched in February 2012 following the closure of the News of the World in the wake of the hacking scandal in July 2011.
Sun publisher News UK said in a statement: "We are looking to build on the success of The Sun's Sunday edition and are therefore searching to find the cream of the journalistic crop as we look to hire 16 new editorial staff to work exclusively on our Sunday paper.
"We will be recruiting talented journalists who will bring fresh energy, skill and new ideas to our newsroom of world-class reporters, writers and editors. There are excellent opportunities on our news, showbiz, sports and features desks.
"At a time when many of our rivals are cutting back this shows The Sun’s commitment to the future of quality journalism has never been greater."
The News of the World employed around 250 staff, about 180 of whom lost their jobs in the wake of its closure. Around 50 journalists were found jobs on The Sun with another 11 workiing on an unspecified digital-only project.
Sun editor David Dinsmore said: "It is an extraordinarily exciting time to be joining the team at Britain's best-selling newspaper.
"We are passionate about supporting and creating jobs so I am delighted that we can offer these new posts to talented people who will drive the success of The Sun on a Sunday to even greater heights."
The 60p Sun Sunday is the UK's best-selling Sunday newspaper and had sales of 1,875,220 in June. But this figure was 14.4 per cent down year on year.
This expansion at The Sun comes weeks after Mail Online revealed it was recruiting an unspecified number of senior editors and journaists ahead of a major UK and international expansion of the site.
