Business minister Richard Harrington said: "I do wish people would stop putting their own dogma above the good of the country and the Party".
The outcome of Friday's meeting is seen as critical to moving Brexit negotiations forward because the European Union have complained that talks have stalled because they do not know enough about Britain wants from its future relationship. We have supported the government's drive to seek the best possible deal for the United Kingdom economy.
