The Liberal Democrats, the SNP and Plaid Cymru have demanded that parliament is recalled to debate the air strikes in Yemen.

Leading figures on the Labour Left agree.

The former shadow Chancellor John McDonnell has warned that the UK and US action could set ‘the region alight’.

But those MPs who want a vote are likely to be disappointed.

As the action has concluded, this is unlikely - though the Prime Minister is expected to give a statement to Parliament on Monday and will seek to reassure MPs that UK involvement was proportionate and legal.
