David Cameron says being PM 'the greatest honour' in final Downing Street speech

David Cameron said being head administrator had been "the best respect" of his life as he arranged to formally leave.

Flanked by his better half and youngsters in Downing Street, he said the UK was "much more grounded" than when he assumed control.

He then went to Buckingham Palace to delicate his renunciation to the Queen, who has now formally named Theresa May as his substitution.

Prior Mr Cameron took PMQs for the last time, telling MPs he would "miss the thunder of the group".

In the wake of taking office, Mrs May, the home secretary, will set about naming her own frontbench group.

"Legislators like to discuss approaches, however at last it's about individuals' lives," he said, indicating the administration's record on occupation, the NHS and resistance.

He wished Mrs May well, saying she would give "solid and stable initiative", and paid tribute to his significant other Samantha and his kids.

As the family left for the last time, he said his lone wish was "proceeded with accomplishment for this incredible nation that I cherish so in particular".
