Gerald Mason, senior vice president of Tate & Lyle Sugars which is one of the UK's oldest firms, has written to staff saying that leaving the EU would benefit the business.
Tate & Lyle Sugars joins campaign to leave EU
"Mr Mason writes: "Last year EU restrictions and tariffs pushed our raw material costs up by nearly 40m euros (£31m) alone, turning what should have been a good profit that we would all share into a 25m euros loss.
'Not democracy'"
""We pay as much as 3.5m euros of import tariffs to the European Union on some of the boats of cane sugar that unload at our refinery, only for the European Union to then send that money to subsidise our beet sugar producing competitors in Europe.""
"Mr Mason said he has challenged EU officials about reforms, but been told "that if we lose our jobs then that's democracy because there are more beet producers than cane refiners in Europe. That is not the sort of democracy I want to be part of"."
