"I must also thank the former Prime Minister, Boris Johnson, who put a great deal of trust in me. I will be forever grateful not only for this but for his kindness and encouragement.

I was delighted that his commitment to delivering the referendum result, his optimism and his vision for levelling up the country and ensuring that life chances are distributed fairly resulted in the seismic election victory of 2019."
