A look at the current London mayor's race gives every indication of a nail-biter with incumbent Ken Livingstone of the Labour Party seeking a third term.

On those two previous occasions Livingstone was compelled to secure victory in a second round of voting.  

A current Sunday Times telephone survey of one thousand Londoners suggests that history will repeat itself once more.  

The result showed incumbent Livingstone with 45 percent of the vote, just a shadow of a nudge ahead of Conservative challenger Boris Johnson with a 44 percent figure.  Liberal candidate and former Metropolitan police commander Brian Paddick received 9 percent.
