A rush-hour collision is causing long queues on a motorway.
The London-bound southbound side of the M40 has seen an accident between Junction 4 for High Wycombe and Junction 3.
One lane has been closed and this is causing delays of more than half and hour, and has led to seven-mile queues.
National Highways says a recovery truck has just arrived.
