Meanwhile in London, taking a cordial tone, Mrs May suggested further talks with the Labour Party leadership even as she said she did not see the advantage of permanent membership in the EU's customs union, a key demand Mr Corbyn is seeking in exchange for backing her troubled Brexit bill in Parliament.
The Secretary of State for International Trade and President of the Board of Trade, The Rt Hon Dr Liam Fox MP, signed the UK-Switzerland agreement in Bern today (Monday 11th February) with Swiss Federal Councillor Guy Parmelin.
In her letter, Mrs May said she wanted discussions between Tory and Labour teams to start considering "alternative arrangements" to the backstop contained within the withdrawal agreement.
May wants to win over lawmakers in her Conservative Party with changes relating to the Northern Irish border, but the EU has refused to reopen that part of the deal and instead wants May to pursue a compromise with the main opposition Labour Party by agreeing closer UK-EU ties.

As companies and governments across Europe step up preparations for the turmoil of a no-deal exit, diplomats and officials said the United Kingdom now faces three main options: a no-deal exit, a last-minute deal or a delay to Brexit.
"It is very clear from the European Union that non-EU members do not have a say in EU trade policy so to pretend that you could do so is a unsafe delusion".
Mr Johnson said Mrs May's priority should be to secure a time limit on the backstop - meant to prevent the return of a hard border on the island of Ireland - before the next election scheduled for June 2022.
"I think that you would need to have a time limit". "That isn't right in terms of the respect for parliament", said Starmer.
Mr Barclay will later travel to Brussels for talks over dinner with the EU's chief negotiator Michel Barnier.
But she said the Government is prepared to commit to asking Parliament if it wishes to follow suit if standards change.
