Tory tax call row.
Leader David Cameron failed to end calls for cuts from right-wingers at the Tory conference in Bournemouth.
But David Mundell, Dumfriesshire, Clydesdale and Tweeddale MP, warned: "These things are not going to happen.
If people want these things to happen, this isn't the party for them."
The Shadow Scottish Secretary's remarks angered hardliners who want to offer tax cuts at the next election.
Edward Leigh, chairman of the right-wing Cornerstone group of MPs, said: "Who is David Mundell? It hardly bears a response."
