Yes you can, but please note that EU debt and debt from countries outside the EU e.g. USA, is treated differently. There are agreements in place among the EU member states that oblige each member to observe the other’s creditors. What this means is that credit card debts, loans, overdrafts and mortgage shortfalls in say, Poland, will be liquidated in a UK bankruptcy. You may include debt from countries outside the EU, but they are not obliged to observe the bankruptcy and the debt may well remain in place. However, the creditors would not be able to pursue you for the debt provided you remained in the UK.
