Leading team JHR suspended from competing in Ginetta categories

Three of the team's Ginetta Junior drivers - including points leader Seb Priaulx - were excluded from the Thruxton meeting for engine irregularities.

JHR successfully appealed the decision at the MSA National Court, but Ginetta feels the court's findings were not "sufficiently comprehensive regards to the conduct of the team in question".

A championship bulletin read: "Safeguarding the good sportsmanship that underpins our championships is our top priority.

"Ginetta is suspending JHR Developments' participation in our championships, pending a further investigation into the conduct of JHR and their employees.

"The investigation will consider whether their actions met our regulatory standards of fairness and were in accord with the principles of good sportsmanship.

"We believe that allowing JHR to continue participating in our championships for the remainder of the season, during the investigation, would unfairly reflect onto their drivers and unreasonably bring into question the veracity of their results."

The team ran eight cars in Ginetta series last weekend, and with all of those drivers now needing new drives, a host of team changes are likely over the coming weeks.

JHR's drivers aren't being investigated and may remain in the categories with other teams.

They include the top two in the Junior points, Priaulx and Tom Gamble, and George Gamble in the GT4 Supercup.

Autosport understands that Priaulx is close to a move to another Ginetta Junior team.

One popular location for frontrunning juniors will likely be HHC. Team boss Charlie Kemp refused to be drawn on any names linked with the team.

"It [the news of JHR's suspension] was a surprise to us all and we are in conversations with a number of JHR drivers," said Kemp.

Ginetta Junior scholarship winner Adam Smalley - who is subsidised by Ginetta, is also with JHR in the Junior series. But Ginetta confirmed to Autosport that Smalley will have a seat by the next round at Rockingham.

JHR boss Steve Hunter was unavailable to comment when Autosport attempted to contact him.
