"It is an absolute shambles that the Tories claimed to have struck a formal deal with the DUP, only to now admit that no such deal was in place. Theresa May's government is in absolute chaos.
"If the Tories do agree a confidence and supply arrangement, the public will have little confidence in it. We must have absolute transparency over what agreements will be reached for the supply of DUP votes.
"It would be nothing short of scandalous if the Tory party jeopardised the return of government in Northern Ireland and the Good Friday process in order to cling on to power at Westminster.
"At the same time there are very real questions to be asked over any suggestion that equal rights for LGBTI people or women's rights could be diminished in any part of the UK by this deal.
"The PM's private reassurances are worthless given her track record of u-turns and her clear desperation to cling to power.
"SNP MPs will always work with other parties in support of progressive policies across the UK and we will demand full scrutiny and transparency over any confidence and supply arrangement."
