AGM 23.05.19: Agenda: Ordinary Business No3

I'm new to shares and don't understand the implications/ramifications of this. If successful will this dilute our shareholding (as a % of the company) in the company by 80%? Will our vote value in the company be reduced by a similar amount? If successful, and there are suddenly 5X the number of shares available, is this likely to impact adversely on the share price? And who owns the extra 400 million shares that are created? Any help clarifying this would be appreciated
