The discussion was about whether John Major right to suggest that the British public should have the right to vote on the final Brexit deal.
But one audience member said he agrees with previous audience members that it only takes “strong leadership” to get a good deal.
The audience member from Blackpool said: “People voted for different reasons. But two members of the audience hit it spot on tonight, it’s about leadership.
“Owen Smith is very eloquent and spoke very well tonight in regard to the Labour position but it is very important that Corbyn has a role to play.
“The flip-flopping by Labour over the last 12 months has been disgraceful really.”
Question Time presenter David Dimbleby said: “What do you make of this change, this apparent change in the Labour policy?”
To which the audience member replied: “There will be another change next week, that’s what we’ve put up within the last 12 months.
“There is no direction, no political direction.”
Mr Dimbleby responded: “They want to stay in a customs union.”
The audience member quipped: “They are this week, but we don’t know whether that’s going to be the same case going forward.
“Each political party has to set out what they believe.
“At the moment you have not got the effective opposition which makes the Government stronger as well.
“I think Theresa is doing the best she can but each political party should play a role.”
Jeremy Corbyn called for a customs union with the EU after Brexit.
He accused the Government of leaving the country “in the dark” and failing to “agree among themselves”.
The Labour leader said his party “respected the result of the referendum” and his priority is to “get the best deal for people’s jobs and the economy”.
He said: “We have long argued that a customs union is a viable option for the final deal so Labour would seek to negotiate a new, comprehensive UK-EU customs union to ensure there are no tariffs with Europe and to help avoid any need whatsoever for a hard border in Northern Ireland.”
