Timeline: May and Gove's row over Birmingham schools

The row between Theresa May and Michael Gove over the handling of the allegations of an Islamist plot to takeover the running of Birmingham schools has led to the resignation of a close aide to the Home Secretary and an apology from the Education Secretary.

Here are some of the key developments in the feud between the Cabinet colleagues:

• November 2013: Mr Gove and Mrs May's dispute began when the Education Secretary called for the definition of extremism to be broadened so more hardline organisations were covered. Mrs May refused, leaving Mr Gove taking his argument to the Prime Minister.

• June 4 2014: On the day of the Queen's Speech, The Times reveals the extent of the row between the ministers. Mrs May questioned whether Mr Gove's department knew about the allegations in 2010 and asked: "If so, why did nobody act?" The duo issue a joint statement in a bid to dampen the story.

• June 5 2014: David Cameron vows to "get to the bottom" of the spat.
• June 6 2014: It emerges Cabinet Secretary Sir Jeremy Heywood is investigating the row for the PM.
• June 7 2014: Mrs May's special adviser Fiona Cunningham quits over comments in The Times and Mr Gove writes a letter of apology.
