Martin Lewis sent a word of warning to Tesco shoppers on last night's Money Show Live.
The Money Saving Expert returned for a new episode of the consumer ITV programme on Tuesday night. The show was a pension special as Martin shared important advice for how people can maximise their benefits.
However, Martin was dealt with a number of last minute changes ahead of the show's broadcast. The finance guru was urging people to fill in any gaps in their National Insurance as the deadline loomed on July 23.
