Theresa May suffered a new humiliation in the House of Commons as the Democratic Unionist Party backed opposition motions on the NHS and tuition fees.
The move by the Labour Party saw MPs push for an increase on NHS pay and to block an increase of £250 a year in tuition fees.
The DUP backed both of these motions, and because the Conservatives do not have a majority, they did not contest them in a vote.
This marks the first time the DUP had broken with the confidence-and-supply deal struck after the result of the General Election in June, in return for which May promised the Northern Irish party additional funding of £1bn.
Even though the Democratic Unionists are not bound to support the Government on the type of motion put forward yesterday, it still represents a symbolic triumph for Labour.
It also serves as a possible indicator Labour will be able to manipulate the relationship between the Tories and the DUP to inflict defeat on the Prime Minister.
