Question Time: Should I overpay my mortgage? If I sign up online, why can’t I cancel online? Can I open an ISA for my niece?

In our Question Time podcast, Martin Lewis answers your questions including: which travel insurance policy do I make a claim to? When you say ‘pay off all debts’ does that include your mortgage? Can I open an ISA for my niece or nephew? Why is cancelling a subscription so hard? Plus, how your height impacts your step count, and what should we call you if you ask us a question? And we have a success story following Martin’s answer to a question on broadband. If you want to ask Martin a question, his Question Time podcast lets you do just that! You can ask him questions about absolutely anything and everything (within reason!) – so if you’ve always wanted to know which tree he likes best, how many burpees he can do in a minute, or have a very complicated question about your personal finances, email it to MartinLewisPodcast@bbc.co.uk.
