Police were also called at 8.15am to reports of protestors near junction 4 (Stanborough Interchange) of the A1(M).

Another 16 people have been arrested, the majority of whom were also glued to the carriageway. A diversion is in place.

Ch Supt Nick Caveney said: “Protestors have made it clear that they intend to continue causing disruption. Not only is purposely blocking a highway incredibly dangerous, it also affects thousands of members of the public who are stuck in delays as a result.

“We have robust plans in place in order to minimise any disruption and to allow us to make arrests as quickly as we possibly can. This includes, but is not limited to, monitoring areas that have been identified as possible protest targets.

“Officers were on the scene within minutes of being alerted to protest activity, allowing us to put diversions in place to ease the traffic and to make numerous arrests. All protestors involved in this morning’s protests have been arrested and will be taken to custody.

“We are working closely with other affected forces to ensure that any further activity is dealt with effectively and efficiently.

“I understand and appreciate the frustration regarding the considerable delays and inconvenience that has occurred as a result of the protests.
