A senior member of Cumbria County Council walked out of a cabinet meeting in protest this morning - and has since quit his post.
Councillor Tim Knowles says that he felt compelled to go as a matter of principle.
His resignation comes a week after the cabinet voted against plans to look for a possible site to bury nuclear waste in the west of the county.
He spoke exclusively to Samantha Parker, and you can watch her full report below.
