Question Time: Best kids’ savings or investments? Pension at 50? Which mortgage to overpay? Snakes, or an angry gorilla?

In our Question Time podcast, Martin Lewis gives you answers on anything and everything, including: why do I pay interest even if I pay off my credit cards in full? Where’s the best place to save and invest for my young children who have pension income from my late husband? I’ve got two mortgages on my house, which should I overpay? What’s the best place for me to start a new pension aged 50? Plus, would Martin rather be locked in an empty shopping centre for 24 hours with 1000 snakes, or one angry gorilla? 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 if he’s got a favourite marsupial, how many miles he could walk backwards, or have a very complicated question about your personal finances, email it to MartinLewisPodcast@bbc.co.uk.
