"But other people on my behalf have felt concerned and have said they have reported it on my behalf and I'm aware there is a sort of feeding frenzy happening and that I may well have to do so in the next few days". May telephoned the European Commission President, Jean-Claude Juncker, Germany Chancellor Angela Merkel, and other EU leaders insisting her government was working to invoke Article 50 by next March.
Brexit offers a "great national opportunity" to "forge a bold, confident global future for Britain", said May, who spoke out in favor of staying within the European Union during the hard-fought referendum campaign.
Setting out his country's response to Thursday's dramatic High Court ruling, the German foreign minister Frank-Walter Steinmeier urged Downing Street to resolve the situation "as quickly as possible".
"There must be transparency and accountability to parliament about the government's plans", he was to say to a think tank in London on Saturday, according to pre-released extracts of the speech.
The High Court decision has fuelled speculation that May might call an early election to strengthen her support in the House of Commons before the European Union vote. Nigel Farage, former leader of the U.K. Independence party, voiced his concern that Britain was heading for a "half Brexit".
In Berlin, British Foreign Minister Boris Johnson said the court ruling should not interfere with the government's Brexit timetable.
It is reasonable to expect that in order to authorise Article 50 being triggered, MPs and peers might want at least a preliminary decision on some of the big, knotty questions that Brexit raises.
Blackpool South MP Gordon Marsden supported the Remain campaign but said bringing Article 50 before Parliament was about giving MPs chance to scrutinise the exit process rather than reversing the outcome of the referendum.
Of course, the more detailed the proposition put to parliament the more time will be spent debating it - which will delay the triggering of Article 50.
Olesen holds nerve to triumph in Turkey
I didn't score that well, but I felt like I was playing a lot better, so I was hoping for something good to come. Having dominated the Turkish Open this week, Thorbjorn Olesen rounded off a deserved win on Sunday.
The pound's surge has suggested the market is hopeful of a softer Brexit, involving free market access, but Curtice says it's too early to draw conclusions.
The case is considered the most important constitutional matter in a generation, pitting the rights of Parliament against those of the executive.
In this way, the court decision has revealed the complexity of leaving the EU. Many are unsure about what kind of future relationship with the EU Britain should have.
In a sign of the likely parliamentary storms ahead, pro-Brexit Conservative lawmaker Stephen Phillips resigned as an MP on Friday, citing "irreconcilable policy differences with the current government".
He said the High Court judges "gave a comprehensive ruling on many points, many of which could cause the government's argument to fail".
"Labour respects the decision of the British people to leave the European Union".
"The focus of the government is on the Supreme Court case, winning that case and proceeding with article 50", May's spokesman told reporters.
He said he was "unable properly to represent the people who elected me".
