Theresa May faces constitutional crisis over Brexit laws

Theresa May is facing a constitutional crisis after Labour and the Liberal Democrats threatened to use the House of Lords to block the crucial legislation that would ensure a smooth Brexit, ignoring  a 72-year Salisbury convention.

The Salisbury Convention states that manifesto commitments made by a governing party should not be blocked or significantly altered by the Lords.

May’s rivals argue that Conservatives party has not won a majority and hasn’t yet reached a deal with the DUP.
