Top Just Stop Oil donor cuts funding, says protests now 'pointless'

Dale Vince, major Just Stop Oil donor, withdraws funding and support for the group.
Vince believes further protests by Just Stop Oil will be ineffective and counterproductive.
Vince will instead support the Just Vote campaign to encourage voting among young people.
Labour has pledged to ban new oil and gas drilling licenses if elected.
Concerns remain over the Conservative government's weakening of climate change efforts.
