As it’s Christmas, Producer Matt has chosen his favourite questions you’ve asked Martin in our Question Time podcast, including: Can I refuse a smart meter? Is paying by PayPal a bigger risk? Should I keep cash under my mattress? Should you invest in gold? Will my new husband need to pay for my daughter’s university? And, would Martin want to fight 1 man-sized duck, or 10 duck-sized men? You’ll have to listen to find out! If you want to ask Martin a question, you now can! His Question Time podcast lets you ask Martin absolutely anything and everything (within reason!) – so if you’ve always wanted to know his favourite radio station, how many marshmallows he can fit in his mouth, or have a very complicated question about your personal finances, email it to MartinLewisPodcast@bbc.co.uk.
