After much speculation the self-proclaimed "saviour of Radio One" Chris Moyles will make his return to the airwaves as breakfast show presenter on the newly-branded replacement for the UK's Xfm station, Radio X.

The Global Group-owned station has also confirmed a raft of new signings including ITV1 prime-time Family Fortunes presenter Vernon Kaye, former Capital breakfast host Johnny Vaughan and, at the weekends, Kaiser Chief frontman and presenter on BBC One's The Voice, Ricky Wilson.

Ashley Tabor, founder and executive president of Global, said: "I've had a great summer hearing some of the funniest rumours I've ever heard. I'm pleased we can now confirm the industry's best kept secret.

"Chris is a broadcasting genius and as Global makes a multimillion pound investment in launching Radio X on a national scale, I couldn't think of anyone better to host the station's breakfast show. Along with Vernon Kay, Johnny Vaughan and Ricky Wilson, the UK has never had a radio station like Radio X before."

Moyles spent much of last year out of the celebrity spotlight due to questions over his financial arrangements including a tax avoidance scheme that was alleged to have netted the DJ up to £1m ($1m). He will return to the air on 21 September from 7.30-11am (BST) on the rebranded station.

Vaughan, who left the Capital breakfast show in November 2011 after nearly eight years in the hot seat, will take on the X drive-time show. The move for the former Big Breakfast host will herald his return to Global, which owns both the Capital and Radio X networks.

Global described Radio X as "the first truly male-focused, fully national music and entertainment brand for 25-44 year olds".

Speaking on Twitter @FionaSturges questioned the lack of female presenting talent on the new station. She said: "Chris Moyles, Vernon Kay and Ricky Wilson confirmed for #RadioX. Should we assume that women will be reading the weather and making the tea?"

Stephen Miron, group chief executive at Global, said: "Radio X will be a one of its kind radio station and the first time the commercial sector has catered for this hard to reach group. Our investment in a national platform, an unbeatable talent line-up and a heavyweight advertising campaign speaks to our ambition for the brand."

Global will launch a new multimillion pound advertising campaign to back the radio station using the strapline "Get into the music". Radio X will be broadcast across the UK on the digital radio platform D1 as well as on 104.9FM in London and 97.7FM in Manchester.
