Douglas Ross has been branded a "super heavyweight" by Michael Gove as the Tories try to draw a halt to the civil war raging in their party.
The Scottish Conservatives leader infuriated his colleagues at Westminster last month when he demanded that Boris Johnson resign as Prime Minister in the wake of the Partygate scandal.
Ross was backed by his MSPs at Holyrood as well as former leader Ruth Davidson - with many privately fearing the scandal-prone PM is a threat to the future of the Union.
