Politics Live - readers' edition: Friday 17 November

I’m not writing my usual blog today but here, as an alternative, is the Politics Live readers’ edition. It is a place for you to discuss today’s politics, and to share links to breaking news and to the most interesting stories and blogs on the web.

Feel free to express your views robustly, but please treat others with respect and don’t resort to abuse. Guardian comment pages are supposed to be a haven from the Twitter/social media rant-orama, not an extension of it.

You can read all today’s Guardian politics stories here.

And here are some of the main ones on our site this morning.

• David Davis, the Brexit secretary, has warned Germany and other European nations not to “put politics above prosperity” as they negotiate the UK’s split from the EU.

• The shadow chancellor, John McDonnell, argued that big business now trusts Labour more than the government on the economy and Brexit as he launched his vision for a budget next week that would involve more investment and an end to austerity.

• Iain Duncan Smith’s thinktank is calling on the chancellor to renege on promised Tory tax cuts and instead plough billions of pounds into universal credit if he wants to help families that are just about managing.

• The government will be more than a decade late in meeting EU targets on air quality, a report from the National Audit Office (NAO) has revealed.

• Scottish Labour is accused of failing to act over harassment allegations against Alex Rowley, after it emerged that the party was made aware of the claims five weeks ago.

On Thursdays local council byelections take place. There were 10 yesterday. Britain Elects has six of the results.
