In a keynote speech in Birmingham, Sir Keir promised “straight leadership” based on the values of “security, prosperity and respect” if his party is returned to power.
He repeatedly emphasised that Labour is a “patriotic party” and that his contract would be a “solemn agreement”, setting out how a good government should conduct itself.
“I am well aware that just because the Tories lose the public’s trust it doesn’t mean Labour simply inherits it. Trust has to be earned. I am confident but not complacent about the task ahead,” he said.
While the UK remains a “great place to live”, he said it is not unpatriotic to point out that the country has flaws.
“On the contrary, the reason we in this party want to correct those flaws is precisely because we are patriotic,” he said.
“I came into politics to make things happen, not just to talk about them. I don’t think politics is a branch of the entertainment industry. I think it’s the serious business of getting things done.
“But I’m afraid at the moment we are going backwards. We have a prime minister who thinks the rules apply to anyone but him.
“Just when trust in government has become a matter of life and death, for the prime minister it has become a matter of what he can get away with.
“I have heard so many heartbreaking stories of people who missed family funerals because they were abiding by the rules. Meanwhile, the prime minister was at a cheese and wine party in Downing Street.”
Sir Keir said he believes the country is entering a “new phase” with the start of the new year as the government has shown itself to be increasingly incompetent.
People are facing rising living costs, with energy bills going up and tax increases due in April, while at the same time they are struggling to get an appointment with a GP and do not feel safe in their streets.
He said his “contract” would ensure people have a “basic right” to feel safe in their own communities, knowing the NHS is there for them when they needed it, while having the opportunity to thrive and prosper.
