"It is difficult not to feel for Mrs May, but politically she misjudged the mood of the country and her party. Two Tory leaders have now gone whose instincts were pro-EU. Either the party learns that lesson or it dies", Farage tweeted in an apparent reference to Andrea Leadsom, the head of the UK parliament's lower house, who stepped down on Wednesday saying she no longer believed that the government's approach would deliver Brexit.
May had been under pressure to step down following backlash from her cabinet against the latest draft of her Brexit plan. UK lawmakers have rejected May's withdrawal agreement, negotiated with Brussels, three times.
According to UK Institute for Government, 21 ministers under May have resigned over Brexit, citing the UK government's inability to deliver and negotiate the terms of the deal as a major loss of confidence in their country's political system.
The United Kingdom was unable to leave the European Union by the original 29 March deadline over lawmakers' staunch opposition to the withdrawal deal. The European Council gave the United Kingdom an extension until 31 October, with an option to leave earlier if parliament passes the deal.
