That reply simply doesn't make sense.
Bakker was registered in the Netherlands. They were never registered at Companies House in the UK. (It's not like the Toys R Us liquidation, where the US and UK companies were separate entities; Bakker was just a single company). Any claims against Bakker should therefore be handled by the liquidator appointed by the Dutch courts. (i.e. Emile ten Berge). It shouldn't matter which countries those claimants are in.
I still suspect that you're wasting your time anyway. When a company goes bust the first people to get any money that's left over are the secured creditors. (e.g. banks who'd loaned the company money against mortgages on their properties). Next in the queue for payments are the preferential creditors, such as employees who have yet to receive their wages or holiday payments. Only then do unsecured creditors, such as you, come into the reckoning (ahead of shareholders). There's often nothing left to pay anything at all to unsecured creditors or they might get back something like two or three pounds for every one hundred pounds that they were owed.
