I want to ask does bno has 居歐權 right now?
No, of all the British Citizenship, British national Oversea is the only British Citizenship that does not have Residence Right in UK and EU. Other citizenship have both UK and/or EU Residence Right.
Talk are being discuss that NOT ONLY to UK but most other EU member for this fairless issue, as BNO still linger with British Nationality but without actually any Nationality Right on it.
Agreeing with Samstang, Lisbon Treaty is a treaty that respect each EU internal politic, so Lisbon Treaty even passed cannot oversee the actual change of any of the EU Member internal Affair. So even Lisbon Treaty Passed with recgonising BNO Citizenship as a Form of formal British Citizenship. IT will not allow BNO Citizenship holder to hold Residence Right in UK.
However, since it (Lisbon Treaty) respect each EU member State'sinternal Affair, if any of the EU member state recongise BNO as a Full British Citizenship as per Lisbon Treaty Guideline, they (Those EU member state) will admit BNO holder as if they hold other form of British Citizenship and give them residence right, for this, this is not something UK can alter as this is other EU member countries's own internal politic. The key is not to have UK recgonise BNO have UK Citizenship, the key is for other EU member to recongise BNO as part of UK Citizenship and act accordingly.
