Frank says:

I became a councillor on Camden Council in 1971. Later on I became leader of the council before becoming an MP in 1979.

1971 was the year London's parks and open spaces were transferred from the GLC to local councils. Some were derelict and they were often small. But to those who lived around them, they had potential as green spaces.

As the chair of the responsible committee at the time, I wanted to put the spaces to good use. But I was also the father of three young children. The result for me? Weekends with my wife, pram and kids visiting dots on the A-Z by bus. The result for local people? New gardens, play areas and small parks, many of which are still used and valued today.

Later on, as the council Leader I drove through a huge programme of house building and renovation in Camden. The homes we created then still serve thousands of families today.

Many of the thousands of street trees we planted then still blossom in the spring.

Thousands still walk and cycle along the Regents Canal towpath we opened to the public.

I'm proud of those achievements. They are the sort of improvements we need all over London.
