Jacob Rees-Mogg says "cave-dwellers in the House of Lords" are seeking to keep the UK in the European Union.
Peers inflicted an embarrassing defeat on Theresa May’s government on Wednesday, challenging her refusal to remain in a customs union with the EU following Britain's departure from the bloc in March 2019.
"The customs union is a means of trying to stop Brexit happening," the Conservative MP told Julia Hartley-Brewer.
"Keep us in the customs union, keep EU tariffs, keep close align with regulations – it means we don't really leave.
"And you saw this in the House of Lords...peers receiving large pensions from the European Union voting to protect their vested interests.
"Consistently, polls have shown that 60 to 70 per cent of people have accepted the result (of the EU referendum) and want us to get on with it.
"There are a few cave-dwellers in the House of Lords who are committed to opposing Brexit altogether, who want to keep us in, who never liked the vote to leave, who are contemptuous of democracy, and they are increasingly out of touch with the mood of the British people.
"It is the peers against the people," he said.
