Ladell had initially announced he would race for Wayne Eason’s squad this year before a sudden switch to Team Cooksport for the opening half of the campaign.
However the 18-year-old from Suffolk has opted to return to WDE for Knockhill’s, Rockingham’s, Silverstone’s and Brands Hatch’s remaining eight races.
Ladell commented: “The appeal of racing for a team run by Josh Cook (last year’s Clio Cup runner-up and now British Touring Car driver) was obvious and I’m very grateful for all his team have done with me in the first half of 2015.
“But equally I’ve always felt WDE is my spiritual home – I’ve done most of my racing career with them, including my first Clio Cup races in 2014. To be back there with a three-time champion (Paul Rivett) as a team-mate, mentor and benchmark is I believe what I need to step up to the next level.”
And added Ladell: “Paul is fourth in the championship at the moment – I want to match him and beat him, just like any driver, but if in the closing stages of the season he has a strong chance of the title then I’d definitely look to help him out on track if he needed it.”
WDE Team Principal Wayne Eason commented: “We’re delighted to have Charlie back. It knocked us sideways a bit when he left at the start of the season, but now he’s back it means Paul has another very fast, proven team-mate to work with. At the same time this will help our other driver Rory Green progress in his first season. Certainly all the signs are that things are about to really click for him.
“Charlie has definitely chosen a good time to come back to us as we really believe we’ve found something extra in recent rounds with a first win of the season at Oulton Park and our first-ever pole position in the Clio Cup at Croft.”
