The public's perceptions of current affairs programs hosted by politicians are the subject of research, according to Ofcom.
Present and former lawmakers like Philip Davies, Esther McVey, Jacob Rees-Mogg, Nadine Dorries, and Nadine Dorries host shows on GB News and Talk TV.
As long as they have been classified as current affairs rather than news, they have been permitted to do so.
However, Ofcom is conducting research to determine whether new regulations are necessary.
In a statement, the regulator said, "Viewers and listeners are at the center of what we do.
"It's critical for us to comprehend first-hand what viewers and listeners believe and feel about the TV and radio content they consume, as well as how perspectives may shift over time, in order to ensure that our broadcasting rules are current and effective.
"Politicians were first subject to regulations regarding program appearances in 2005. We are conducting research to determine current viewer attitudes toward these programs in light of the rise in the number of current affairs programs hosted by elected officials and the recent public interest in this issue. ".
According to Ofcom's regulations, politicians are not permitted to read the news, conduct interviews, or serve as reporters for news programs "unless, exceptionally, it is editorially justified.".
However, as long as a variety of viewpoints are represented, they are permitted to host current affairs programs.
Politicians have been fronting or making guest appearances on current affairs shows more frequently in recent years.
This is partially a result of the numerous new TV networks that have debuted, including GB News and Talk TV.
The former leader of UKIP and current president of Reform UK (previously the Brexit Party), Nigel Farage, is one of the hosts on GB News. He hosts an evening show from Monday through Thursday.
Rees-Mogg, the host of the show that follows Farage, and the husband-and-wife team of Conservative MPs McVey and Davies, who co-host a Saturday morning program, are also found on the network.
In a previous statement, Ofcom said it would look into an episode of the couple's weekend show in which they spoke with Chancellor Jeremy Hunt about his budget.
Recent years have also seen the emergence of new radio networks, such as Times Radio, which now features former Scottish Conservative leader Ruth Davidson and former Conservative culture minister Ed Vaizey among its staff.
The guest hosting of existing programs on major networks by current or former politicians has also become more commonplace; an example of this is Ed Balls co-hosting ITV's Good Morning Britain.
Former leaders of the Labour and Conservative parties, Sir Iain Duncan Smith and Ed Miliband, have both appeared as guests on the Jeremy Vine show on BBC Radio 2.
Media commentators have questioned whether Ofcom rules governing current affairs programs should be tightened to reflect the stringent regulations that govern news output.
