THE SNP’S deputy Westminster leader has reacted with astonishment after a Tory minister accused her party of misleading church leaders about Brexit.

Kirsten Oswald urged the UK Government to provide reassurance after Scottish religious figures united to condemn Downing Street plans to break international law.

The Church of Scotland, Roman Catholic Church and Scottish Episcopal Church have come together in a joint plea over the controversial Brexit legislation. They're joined by the United Reform Church, the Methodist Church and the Quakers.

In a joint letter sent to UK lawmakers, they say proceeding with the bill would set a "disastrous precedent" and risks the devolution settlement.

The issue was raised in the Commons as MPs questioned Northern Ireland Office minister Robin Walker.

Oswald noted that the churches were “united in their concern at the UK Government’s actions on Brexit, with its plan to break international law, acting on devolved matters against the wishes of devolved administrations and placing the peace process in Northern Ireland in peril – a concern they say is shared by church leaders across the Irish Sea”.

The SNP MP asked: “What can the minister say to reassure these representatives of Scotland’s faith communities that his government is listening to anyone as it careers forward on its misguided path?”

Walker insisted that his government was committed to upholding the Good Friday Agreement.

Addressing the concerns of church leaders, he said: “I’m afraid some of the people may have been misled by some of the statements by the SNP rather than raising concerns about what is the reality of the government’s intention.”

Oswald later rubbished the Northern Ireland Office minister’s assertion on social media.

She tweeted: “My face says it all. This was an utterly outrageous response from the Minister to the legitimate concerns raised by Church leaders.”

The letter from the church leaders calls on MPs and peers to debate concerns about the Internal Market Bill – which has been condemned as a power grab by the Scottish Government and rejected by MSPs – and make representations to Downing Street.

It states: "The passing of this legislation by the United Kingdom parliament without the consent of the Scottish Parliament clearly strains the devolution settlement.

"The fracturing of an established relationship is in itself something to be regretted because it is vital that all levels of government work together in the interests of the communities we serve."
