Tory MPs have been accused of sending "deliberately misleading" to locals, which critics say suggest they come from the Green Party.
A campaign group has written to Conservative chairman Nadhim Zahawi demanding activists stop distributing the leaflets and overhaul rules about campaign material.
The leaflets, distributed across the country, feature various shades of green and include pictures of Tory MPs and their names - but without saying they are Conservatives, though there are references to the “Government”.
