As a peer Business Secretary Lord Mandelson is unable to face Clarke in the Commons – leaving Pat McFadden (right) and Ian Pearson to face up to the Tory big beast.
But Clarke, with years of debating experience, has so far come out on top of his clashes with Mandelson’s underlings.
The shadow business secretary told Lobbydog: “They have no political clout – they are not the real source of authority in their department.

“But no-one would put [McFadden and Pearson] forward as advocates particularly, because neither of them are heavy-weights.”
Rushcliffe MP Clarke added: “They are rather obscure ministers.”
He explained that he liked and had respect for “Peter”.
But the jibes will be seen as a direct challenge to Mandelson who has so far shrugged off the idea of a televised debate between him and Clarke.

“I’ve made that clear to the television companies – my guess is that those companies would love to put us together for a debate.
“But he won’t go on TV.”
