It was a tough choice [of PM]. I voted for a Scotsman.

The challenges facing Britain required not just a cool head, but a heart burning with the desire for change - not business as usual but a bold vision.

With the single exception of Park Lane, every north-south route in London slows traffic to the pace of a wounded gnat with pleurisy struggling with a squaddie's backpack.

I believed we needed someone who would be able to build a team, lead and unite. I hoped that person would be Boris Johnson.

One of the problems we have is children are not in school long enough in the day and during the year.

We need a national ambition to build hundreds of thousands of new homes a year, both private and socially-rented - led by someone who will not take no for an answer and who will push for diggers in the ground and homes for all come what may.

It's often the case that successful people invite criticism.
