A former homeless person has gone from the street to a seat and been crowned London's top bus driver - because he never stops smiling. Pat Lawson is over the moon after being crowned the most bubbly bus driver in the capital, despite having to battle through gridlocked traffic on a daily basis. The 50-year-old admits he never stops smiling, after finally landing on his feet, following periods of homelessness, and even prison. After falling into the "wrong crowd" as a teenager and a spell in prison, Pat was dragged into the "dark and vicious cycle" of homelessness, crime and drugs. From selling the Big Issue and searching London's streets for somewhere to sleep, optimistic Pat can now be find cheerily greeting passengers on the 26 bus from Hackney Wick to Waterloo.
