when starting our business there was a huge risk for me as I was putting in all the money with no track record of what this new business could make and that is why i have a majority shareholding in our business but now that the business is doing very well he has shown our figures to an investor who has promised him that if he goes on his own they will back him and he can be majority shareholder in the new venture.They will be stealing my suppliers and selling to my customers.Is this bad business practise.
