BBC Radio 4's Inside Money lets listeners explore the financial issues that matter to them.

Each week, presenter Lesley Curwen will offer her low-down on making the programme.

Joining Inside Money as a Radio 4 listener can be exciting, and dare I say it, nerve-racking.

For example - what on earth should you wear when interviewing the governor of the Bank of England?

Our listener, Adam Potter, decided to don a dark suit, and a smart new shirt and tie.

He had travelled down for the occasion from Stockton on Tees where he runs a small engineering business.

Adam contacted the BBC because he was worried that inflation was running out of control. We asked him to join us to make a programme about those concerns.

And that is how he ended up walking into the grand, fortress-like entrance to the Bank of England.

As the icing on the cake, Adam was shown the spacious room where the Bank decides on the UK's interest rates

A large man in a pink tail-coat greeted us as we arrived and searched our bags, apparently looking "for any spare sweets" we might have on us.

It was, I have to say, one of the biggest coups Inside Money has ever pulled off.

I have been presenting the programme for the last seven years, and if you have ever listened to an edition, you will know we try to "take our listeners to the very top" to get their queries and complaints addressed.

That has often meant meeting government ministers and chief executives, but never before the man at the helm of the UK's monetary policy framework.

And the timing was impeccable - the programme would be transmitted soon after the Bank had decided on another rise in interest rates, in its July meeting.

Adam Potter had been given a chance many journalists of my acquaintance would donate a right arm for - a face-to-face meeting with Mervyn King, who rarely gives broadcast interviews.

He was able to question the governor about the importance of controversial factors in interest rate decisions, such as the housing market and money supply figures.

Mervyn King was friendly, welcoming and formidably precise in his answers.

And, as the icing on the cake, Adam was shown the spacious room where the Bank's Monetary Policy Committee decides on the UK's interest rates every month.

He saw the unexpected green flash of the garden which lies at the heart of Bank, and he walked over elaborate mosaic paving, decorated with the old fashioned signs for pounds, shillings and pence.

For me, being in the Bank reminded me of the last time I had met Mervyn King.

It was in 2000, when he was deputy governor and I was making a series called "The Old Lady" for Radio 4.

Back then, he had told me about the birth of the Monetary Policy Committee, when there was a "tremendous sense of elation" that the Bank had been given independence to set interest rates, but also the sense of "an enormous challenge".

It was now a decade since the Bank had been given the job.

As I sat there with Adam, I asked the governor if he was proud of what the MPC had achieved.

"Yes," he said. "Anything more to add?" I ventured.

He told me he saw no reason why the MPC should not be successful for another 10 years and decades after that.

Although he was quick to add that he "certainly won't be around then".

It was the end of an extraordinary and heady day. One that our listener Adam Potter will not forget.
