Corbyn faces opposition from at least 60 MPs to a customs pact with May without a second vote
'Jeremy Corbyn will not be able to get enough of his MPs to back a Brexit deal without the promise of a second referendum, even if Theresa May makes a big offer on a customs union and workers’ rights this week, senior Labour figures believe.
Senior party sources said they believe two-thirds of Labour MPs, including several shadow cabinet ministers and many more frontbenchers, would refuse to back a deal without a people’s vote attached.
Theresa May is preparing to make new proposals of a temporary customs union until the next election, matching EU employment rights in the future and alignment of single market regulations on goods.
The prime minister wrote an article in the Mail on Sunday urging Labour to “put our differences aside for a moment” to do a deal when negotiators meet on Tuesday, while Corbyn said after the local election results that voters wanted MPs to “get a deal done” on Brexit.
John McDonnell, the shadow chancellor, had said on Friday that the election results meant voters were saying “sort it” on Brexit but he sounded a more cautious note about the prospect of a deal on Sunday, telling the BBC’s Andrew Marr Show that he had no trust in May and accusing her of negotiating in “bad faith”.
He said any customs union would need to be permanent and warned No 10 that “to get any deal over the line you’ve got to recognise there will be a large number of MPs in parliament who actually do support a public vote”.'
