Here's some more reaction from Chancellor Rachel Reeves, after her earlier remarks.
"The growth numbers have come in higher than many expected, but I'm still not satisfied with the level of growth that our economy is achieving," she says.
"And that's why I am determined to go further and faster in delivering the economic growth and the improvements in living standards that our country deserves.
"We are doing what is necessary to bring stability back to the economy, reforming the economy, the planning system, regulation and pensions to encourage investment in our economy, which is the lifeblood of a successful economy.
"We need to go further and faster in doing that, to turn around our poor growth performance and to make working people better off."
On whether the government may need to cut spending or increase taxes to meet fiscal rules, she says: "The Office of Budget Responsibility will publish their updated forecast on 26 March and I will respond to it then.
"I have been clear that the fiscal rules are non-negotiable, and that's because stability is absolutely essential for returning growth to our economy.
"We've seen three cuts in interest rates since this government took office in July. That's only possible because of the stability that this government have returned to the economy."
