I have come, reluctantly, to the conclusion that Boris [Johnson] cannot provide the leadership or build the team for the task ahead.

If we are to make the most of the opportunities ahead we need a bold break with the past.

I will put my heart and soul into making sure that the care your son or daughter or mum or dad receives is the same I would want for my own family.

Boris Johnson is a man of great attributes and great qualities.

The first four months of my life were spent in care, before I was adopted by my wonderful parents - my mum and dad - Ernie and Christine. They went on to adopt my sister, who is profoundly deaf, and invested both of us with a love and support that informs everything I do today.

I know what it's like to see someone lose their job as a result of the European Union. I saw my father lose his job, I saw his business go to the wall, I saw 24 people who he employed also lose their jobs.

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.
