At least 10 senior Conservatives tipped for leadership fight

Boris Johnson has said: "EU citizens living in (the UK) will have their rights fully protected, and the same goes for British citizens living in the EU."

Boris Johnson and Theresa May are leading a pack of at least 10 senior Conservatives tipped to be contenders in the battle to succeed David Cameron as Prime Minister of the UK.

Brexit campaign frontman Johnson summoned friendly Tory MPs to his Oxfordshire home on Sunday in likely preparation for a run at the party's leadership, as the British Home Secretary Theresa May was reportedly sounding out colleagues.
