If I were to return to the UK well before my current non O multiple expires,would I be granted a new one?I understand:

1.I must of course meet the criteria.

2.My current visa would be null and void.

Is this possible?Thanks.

Yep if you qualify.

Your current Visa would be cancelled.

Bloody Hell!That was quick!Just want to get over there before I have to sell my family into slavery to pay the cost of the air ticket.

Would it be the same Consulate that issued your present visa? If not have seen reports another Consulate may not want to cancel or issue another visa with a current visa in passport. That said you are aware such visas are available for those married to Thai in KL with simple proof of 100k in a bank account?
