A minister had to be freed from a farm during an official visit, after an anti-HS2 campaigner locked a gate to try to prevent her from leaving.
HS2 Minister Nus Ghani was in Kenilworth to outline plans for a so-called "green corridor" - planting seven million new trees and shrubbery along the phase one route between London and Birmingham.
Joe Rukin, from the Stop HS2 campaign group, says he wanted to hand an envelope to Ms Ghani containing a complaint.
He locked the gate to the farm, refusing to open it until Ms Ghani agreed to take the envelope. She refused.
He earlier interrupted her planting a tree.
Someone was eventually called in to unlock the gate to free the minister.
