New Brunswick's Liberal Party has removed a video from its website and YouTube channel because it violated a long-standing convention of the provincial legislature. 

The video showed Liberal Leader Susan Holt walking through the main legislative assembly building as she described the party's vision for New Brunswick before Premier Blaine Higgs's state of the province speech in January.

Holt's use of the legislature as a backdrop violated an unofficial rule that the location can't be used for political party activities.

"Upon request from the Speaker's Office, we removed the video," said spokesperson Katie Beers. "We have no further comment."

Speaker Bill Oliver's office asked the Liberals to remove the video, a party spokesperson said. (CBC)

Speaker Bill Oliver would not comment on the video.

It was posted to the Liberal party's YouTube channel, and a Jan. 23 news release on the party website linked to it.

The video is now gone.

The convention also prohibits party events on the grounds of the legislature.

2006, then-provincial NDP leader Allison Brewer tried to hold an election campaign event on the steps of the legislature, complete with orange party campaign signs.

They were told by security staff that party events weren't allowed there.

As of Thursday, a photo of Holt outside the front door of the legislature remained on the Jan. 23 release on the party website.
