British MPs have rejected all eight alternative Brexit options in indicative votes in the House of Commons.

The votes were an attempt to break the parliamentary deadlock over British Prime Minister Theresa May’s proposed Brexit deal.

The indicative votes were as follows:

  • Leave the EU on 12 April without a deal - Defeated 400-160
  • An enhanced Norway-style deal that would include membership of the EU's single market as well as a customs arrangement with the EU – Defeated 283-188
  • Remain a member of the European Economic Area (EEA) and reapply to join the European Free Trade Association (EFTA) – Defeated 377-65
  • A Brexit deal which must include, as a minimum, a commitment to negotiate a permanent and comprehensive UK-wide customs union with the EU - Defeated 272-264
  • Opposition Labour Party plan for a close economic relationship with the EU, including a comprehensive customs union and close alignment with the single market – Defeated 307-237
  • Revoking Article 50 if parliament does not consent to leaving without a deal – Defeated 293-184
  • Confirmatory referendum to approve Brexit deal before it is ratified by parliament – Defeated 295-268
  • A managed 'no-deal' process in the event an exit agreement with the EU is not reached – Defeated 422-139

In a separate vote, the House of Commons approved by 441 votes to 105 secondary legislation to provide for delaying the date of Brexit from this Friday to either 12 April or 22 May.

Meanwhile, Brexit Secretary Stephen Barclay has said that due to the fact none of the alternative Brexit options won the support of a majority, Mrs May's deal was the best option.

"The results of the process this House (of Commons) has gone through today strengthens our view that the deal the government has negotiated is the best option," he told parliament.

Earlier, she said that she will stand down as prime minister if her deal is backed by MPs in a third so-called "meaningful vote".

She said: "I have heard very clearly the mood of the parliamentary party.

"I know there is a desire for a new approach - and new leadership - in the second phase of the Brexit negotiations - and I won't stand in the way of that."

Mrs May did not name a date for her departure from 10 Downing Street, but her announcement sets the stage for a likely Conservative leadership election within the coming weeks or months.

A steady stream of Eurosceptics have signalled they will now support the deal, with Boris Johnson the most prominent to perform a U-turn.

The former foreign secretary, who once likened the deal to a "suicide vest" around the British constitution, told the Daily Telegraph he was "very, very sorry" to have changed his mind.

However, the DUP said it "cannot sign up" to the deal because of the backstop provisions designed to prevent a hard border.
