John Bundy, once the trademark voice of the Nationalist Party media, has moved his breakfast show to One TV.
Labour leader Joseph Muscat personally approached the popular presenter, who stood as a PN candidate in the 1996 election.
"Circumstances change. Today we respect each other's political beliefs more than we ever did... And I give a service to everybody," Mr Bundy told The Sunday Times.
Mr Bundy is a free agent following his rift with production house Dee Media. His new programme, called Bonġu Bundy, will go on air in October.
The programme was initially submitted to the State television station, PBS, but it was turned down before discussions with One TV were finalised last Thursday.
"I don't see anything odd in presenting a programme on One TV. I'm doing this on a professional level," he said.
Mr Bundy, who left the PN's Medialink in 2001 after a well-publicised row with the station's management, underlined there would be no political content in the programme.
He heaped praise on the PL leader, saying he showed true professionalism in dealing with the matter to the extent that he even gave PBS the right of first refusal.
Asked whether he feared he was being used by Labour to entice disgruntled Nationalist supporters to One TV and eventually to the PL, Mr Bundy said: "I'm 49 and I believe I'm mature enough. Nobody uses me and Dr Muscat himself made it clear to me that it wasn't the case. This decision had no political motives behind it.
"I want to work hard to rid us of the political overtones. Broadcasting is my profession and I have to earn a living."
He was reluctant to draw comparisons with former Labour minister Joe Grima, who was given a discussion programme on Net TV, to the chagrin of several diehard PN supporters.
"Mr Grima was a Labour minister. I never was. I was simply employed with the PN."
He also denied being a PN hardliner, recalling that he came up with the popular song Pajjiż tal-Mickey Mouse when his own party was in government.
Mr Bundy also said he had used a toilet flushing sound on his radio show to refer to uncouth listeners and not to Labour supporters, contrary to popular belief. The stunt had been rebuked by the Broadcasting Authority.
One TV boasts a loyal audience, with viewership numbers close to PBS's, Mr Bundy said.
When contacted, Bonġu Bundy's executive producers 26th frame confirmed that an agreement had been reached with One TV.
A spokesman said: "For reasons still unknown to us and Mr Bundy, the programme itself was turned down by PBS. Every company needs to earn a living... this is simply what we are trying to do."
