British Prime Minister Theresa May called for an early election on June 8, saying the government had the right plan for negotiating the terms of Britain's exit from the European Union and she needed political unity in United Kingdom.  The negotiations will cover issues like trade, defence and economic resources. A larger mandate would give more space for her to move ahead with her government’s plans.

To go for early polls, the Prime Minister will need to get the approval of 2/3rd majority in vote in Parliament which see is likely to get.

May was made PM in July 2016. She took over from former Prime Minister David Cameron who stepped down as PM last June when Britain voted for an exit from the European Union. Brexit, as it is popularly called, the process for formal exit from the European Union kicked off from last month.  It is possible that May would seek to gain a larger mandate for herself and increase her Conservative Party’s slim lead in the House of Commons. May’s party currently holds 330 out of 650 seats in the lower house of the British Parliament.

Need for if 2/3rd majority in parliament to call for early elections
Till 2011, British prime ministers had the authority to call polls. After the Fixed-Term Parliaments Act was passed in 2011, the general election are to be held every five years, in May. The PM can call for the early poll if 2/3rd majority in parliament supports it.
