He adds several Conservative MPs would be keen on such alliance but adds that it would also lead to resignations from others in the Conservative Party.

The outgoing prime minister struck a conciliatory, supportive tone from Mrs May in her words outside Number 10.
She emphasised the work of not only hers, but the previous Conservative government – perhaps a reminder to her successor that they will be one part of a much longer story and a much bigger, political picture.

It was a brief statement by Theresa May – but familiar in tone.
She emphasised economic growth, high employment and her pride at being the UK’s second female prime minister.
No tears this time or any talk of regret – but a “new beginning” and a “brighter future” once Brexit had been delivered.
Mrs May paused as, from the distance, an ominous shout of “stop Brexit” was heard.
“I think not” she retorted, with a smile.
She knows it will define her legacy, and even at the last moment there was no avoiding that.

"Thank you for putting your faith in me, and for giving me the chance to serve," she says.
"This is a country of aspiration and of opportunity," she states, adding that she hopes that every young girl has been inspired by her.
She pays tribute to her husband, Philip, and says she will do all she can to "serve the national interest" and a "country that works for everyone".
David Gauke said he resigned as justice secretary because he cannot support Boris Johnson in his "do or die" commitment to leave the EU by 31 October.
He said he strongly supported Theresa May's efforts to "deliver a smooth and orderly" Brexit and her move not to defy Parliament by leaving without a deal before the 29 March deadline.
"Of course, we will now have a new prime minister and I join you in wishing Boris Johnson well," he wrote.
"I very much hope he will achieve his objective of concluding a deal with the EU that Parliament will support.
"In my view, the only responsible way to honour the 2016 referendum result is to leave the EU with a deal and, without such a deal, I fear for the prosperity, security and unity of the United Kingdom.
"Given Boris's stated policy of leaving the EU by October 31 at all costs, I am not willing to serve in his government. I believe I can most effectively make the case against a no-deal Brexit from the backbenches."
