Two lanes of the M1 have been closed northbound between junctions 29A and 30 due to a multi-vehicle accident.

The incident, which happened shortly after 4pm, involved a lorry and at least one other vehicle and the Highways Agency says delays are already building.

5pm update: All lanes of the motorway are now reopen. Long delays remain but should start to ease now.
