Answer: Limited companies do not go bankrupt, they may go into administration and liquidation/receivership, but bankruptcy is fo individuals.
If a LTD company goes bust, it does not affect the Director unless they have guaranteed or co-signed for any of the company's debts. If so, then the Director is now fully responsible for those debts. This does not mean they cannot set-up a new company, but if the Director needs to go bankrupt, as a bankrupt they cannot be a Director of a LTD company. They can be self-employed and trade as a sole trader, but not a Director.
