Heather Stewart is joined by Rafael Behr, Anne Perkins and Andrew Roth in Moscow to discuss the government’s response to the nerve agent attack on the former Russian spy and his daughter in Salisbury. Plus Paul Johnson of the Institute for Fiscal Studies on the chancellor’s low-key spring statement

The nerve agent attack in Salisbury on a former Russian spy and his daughter has provoked a diplomatic backlash in Britain.

We hear from the Conservative chair of the foreign affairs select committee Tom Tugendhat.

The government responded by expelling 23 Russian diplomats but Labour leader Jeremy Corbyn has urged for a more cautious approach in examining the evidence.

Joining Heather Stewart to discuss it all are our columnist Rafael Behr, deputy political editor Anne Perkins and our Moscow correspondent Andrew Roth.

Also this week: blink and you may have missed it. The chancellor’s spring statement was a short and sweet, with upgraded economic projections. Paul Johnson of the Institute for Fiscal Studies gives his take.
