Petar Lekarski
Assistant Editor – News & Investigations

Petar joined MoneySavingExpert in 2019, but his passion for all things MoneySaving goes back much further – as evidenced by his 'Part of the furniture' badge on the MSE Forum.

He developed his in-depth knowledge of bank accounts, credit cards, loans and savings in the Money team before moving across to MSE News. He has written about a wide range of personal finance topics, covering everything from mobile roaming charges to supermarket loyalty schemes to railcards.

In 2021, Petar researched and wrote MSE's comprehensive and massively popular guide to diesel emissions legal claims, and he continues to maintain it as the cases progress.

Petar has also worked directly with Martin Lewis as his researcher, supporting the MoneySavingExpert with his eponymous ITV show and other media appearances over a period of 18 months.

When he's not polishing prose or crunching numbers, you'll find Petar at the cinema, eating spicy food or cycling around London on a rented bike. He also enjoys playing video games, bouldering and lists of three.
