A car came at half past midnight to whisk me off to LBC.

Through the Night with Mike Mendoza was the programme – a night phone-in for the insomniacs of the capital. I love the intimacy and womb-like feeling of radio studios, particularly at this hour – in the dead of the night.

Loads of people telephoning in, and the presenter Mike Mendoza was experienced in handling the variety of human life with care and consideration. One woman phoned about how people who aren’t well and have to go to hospital should be exempt from the congestion charge and rambled fairly incoherently on about her experiences. Mike passed me a note just tipping me that she had cancer and was undergoing chemotherapy. Peoples’ lives are so complex.

Most of the questions were quite political – and for once as I was there as a LibDem I could give political answers – and not in the usual 30 second soundbite way: I had an hour and a half. Complete bliss!
