BBC staff are reportedly feeling uneasy and awkward after Dan Walker's replacement were named.
It has been claimed the BBC Breakfast presenter's replacement has already been chosen, despite applications allegedly continuing.
Dan, 45, had recently left the morning show to become part of the Channel 5 News team.
Applications for the presenting role were shown on the BBC website and closed on May 24.
Interviews for the role are apparently still ongoing and no official announcement has been made as of yet.
However, BBC Breakfast's Twitter account had updated its cover image to include Naga Munchetty, Charlie Stayt and Sally Nugent alongside Jon Kay.
A source claimed to Daily Star : "Much as everyone thinks Jon Kay is the heir apparent for Dan's job, there has been some uneasiness that the 'header' picture for the official BBC Breakfast Twitter account has been changed in the last few days (while the process is still ongoing) to include Jon as one of the four main stars.
The source added that some people felt like bosses could have 'waited' a while before changing the header. It also made some people feel 'uneasy'.
They continued: "There is a bit of awkwardness that the bosses have put Jon in this situation.
"He is well-liked but there's a feeling they've been a bit hasty and now it looks like a done deal before the process has even got going."
Mirror have contacted the BBC for comment.
Dan shared the news of him quitting BBC Breakfast in early April on Twitter.
Appearing in a video on Twitter, shared by Channel 5 News, he told viewers: "Hello, it's Dan here. I have a little bit of news for you. In the next few weeks, I'm going to be leaving BBC Breakfast and moving to 5 News and to Channel 5.

"I'm really excited but this has also been a massive decision for me because I love BBC Breakfast, I love working alongside Sally [Nugent] and I love the team there.
"But Channel 5 came with big ambitions, with big plans and I don't think opportunities like this come around very often and I can't wait.
"I've also had the incredibly privilege of working on some iconic programmes over the last few years, both at the BBC and elsewhere and what I love about this deal is I not only get to present the news, but also host a whole range of programmes right across the channel.
"And what an honour to step into the shoes of Sian Williams. I know how popular she is with both the team and also the audience, so all I can say is I will do my very best to maintain her incredibly high standards.
"Thank you for watching and I'll see you soon on a TV screen somewhere."
