But can she call an election?
"After the 2010 general election, the
coalition government enacted the
Fixed-term Parliaments Act 2011 which set fixed term parliaments of five years. Thus the
next general election was held on 7 May 2015, with subsequent elections held every five years thereafter on the first Thursday in May. However the Act also contains provisions for Parliament to be dissolved and an early election held if no government can be formed within 14 days after a
vote of no confidence in the government. Similarly, the Act allows for an election to be triggered by a vote of two-thirds of MPs in the House of Commons calling for one."
