bmi diamond club - Account Anniversary and Gold card/Vouchers

Advice please.

Given that it's unlikely I'll ever be BD Gold again (Now BA Gold and almost all BA travel), and BD Silver means very little anymore. When my Gold Anniversary is up mid April, the card expires 05/07.

In short, do I still get *G benefits until the end of May, (I might take one last Long-Haul in May) and how do I stand with using up a Gold voucher and lounge access on that day. Voucher question more important as I can always use the BA lounge at MAN T3.
Thanks :-:

Provided you have the old-style gold vouchers with no expiry date then you can use them right up until the last day of May. And yes, you get all the other Gold benefits up until then too.
