Hello and welcome to this special edition of the Week in Westminster.

Parliament had packed up for the Easter holidays,

but MPs and members of the House of Lords were abruptly summoned back

for an emergency sitting on the future of British Steel.

The government's not fully rennationalising the company just yet,

but is bringing in legislation which allows ministers to take control of it.

The Prime Minister has warned that the future of an industry vital to the national interest

is hanging in the balance.

We'll bring you coverage of the opening speeches from the Commons debate

and hear from a former business secretary on the viability of steelmaking in the UK.

And to help us understand the issues at stake, I'm joined by three journalists

who've been closely following the travails of British Steel.

They are the political editor of the Financial Times, George Parker,

the Guardian's Whitehall editor, Rowena Mason,

and the Times columnist Sebastian Payne.

Welcome all of you.

What's the urgency?
