A vehicle fire has led to long delays on the M20, with one lane shut on the stretch where Operation Brock is in place. Lane one of two is out of action on the motorway London-bound between Junction 9 for Ashford and Junction 8 for Leeds Castle at Maidstone. A recovery vehicle is en route and the fire service has been contacted for comment. Delays could last into the afternoon as Operation Brock remains in force meaning just one lane is in use along this stretch of the motorway. Listen to kmfm for travel updates. More as we get it.
