The audience between May and the head of state at Buckingham Palace was purely symbolic. Traditionally, a prime minister was required to ask the monarch to dissolve parliament, but the 2011 Fixed-Term Parliaments Act made the process automatic. May's Conservatives are expecting to increase their majority in the 650-seat House of Commons next month, as opinion polls give them a double-digit led over the opposition Labour party.
After the election, the queen will summon the figure best-placed to command the confidence of the Commons - likely the leader of the largest party - and invite them to form a government as prime minister. The new parliament will meet on June 13, when MPs will elect a new speaker. The formal state opening of parliament by the queen, a ceremony full of pomp, will take place on June 19.
