Second degree - medicine

Can you help me?

I already have a degree (BA 1996 Languages) and an MPhil (1998 Archaeology) though I didn't use Student loans for funding of any sort. After a stint in the military, I now want a complete change in career and study medicine (2017 entry).

However, this is dependant upon funding as without it I couldn't do it - I've read funding is for first degrees only, so am I likely to be able to get a loan for fees and maintenance or will I get nothing?

I have a wife and 2 children if this helps!

Thanks
