Four of the top five best-performing news sites reported a decline in traffic in June, with the Telegraph online hardest hit.

According to UKOM data recently released by comScore MMX, the UK’s desktop-only online population continued to steady at 45.1 million unique visitors in the month of May.

The start of the summer has seen most newspaper sales decline, with only a few titles bucking the trend according to the latest ABC circulation results.

Telegraph Online was up by 23% in May to close in on the 5 million mark, while a 16.3% rise in average unique daily browsers netted Trinity Mirror Nationals an extra 610,000.

Perhaps as a result of the election, May was a reasonably stable month for national newspapers – with a rare sight of (very modest) growth in the Sunday market. Here are Newsline’s key take-outs.

The Daily Mail continues its unrivalled dominance with a combined print, PC and mobile readership of 29 million, with mobile now accounting for a significantly higher proportion of its readership than print and PC.

The latest findings from NRS PADD, which cover the period April 2014 – March 2015, paint a healthy picture for magazines, with mobile and tablet playing an increasingly significant part in magazine readership.

In its second consecutive month of decline, MailOnline was down -2.32%, keeping its total audience under 14 million.

The relentless general election coverage during April appears to have had little impact on national newspaper circulations, according to the latest ABC release, with no titles recording any significant changes.

While the majority of online news sites saw browsers step outside for some sunshine, the Telegraph, Independent and Metro all recorded healthy boosts to their online audiences.
