Thanks for sticking with us for what has been a fascinating, and at times almost poignant, few hours, as Harriet Harman bids adieu to the despatch box and MPs paid tribute to HM the Queen as she becomes our longest-serving Monarch. You can continue to follow the latest developments in the Labour leadership contest, the migrant crisis and the rest of today's political stories on the BBC News Channel and website.

Jean Claude Juncker expresses his gratitude to European Parliament President Martin Schulz by planting a smacker on his forehead. Is Nigel Farage aghast at this most un-British display of emotion or wondering if it's his turn next?   

The Daily Politics

Harriet Harman is presented with a Daily Politics mug by our Adam Fleming in recognition of her long service. She promises to go "out on the lash" with a cup of tea.

The Daily Politics

After her last PMQs and as she prepares to stand down as acting Labour leader, Harriet Harman is reflecting on her nearly three decades at the forefront of Labour politics. She says it is a "massive relief" that she can hand over the torch to someone else, as to be leader full time is a "hell of a thing to do". "It is such a responsibility and a massive relief that someone else can do it". Asked by host Andrew Neil whether she will now have more time to come on Daily Politics as a backbencher, she jokes "we'll see about that". 

Harriet Harman: “largest movement of people across Europe since the second world war”

It’s not clear that any one agency or international organisation has calculated or checked this figure.

But what we do know is:

Almost 400,000 migrants have arrived in Europe through the Mediterranean this year, according to the International Organisation for Migration (IOM). That’s the largest number in recent history.

The biggest displacement of people in Europe after the WWII took place during the wars in the former Yugoslavia in the 1990s.  

The conflicts in Croatia and Bosnia in 1992-95 displaced more than two million, both internally and externally. Kosovo crisis and war in 1999 displaced almost a million people, who stayed in the region, largely in Macedonia and Albania. The EU countries, including the UK, airlifted thousands of them and gave them asylum.

Here's confirmation that the new Labour leader will be on Andrew Marr on Sunday but who will it be..?

Reacting to PMQs, the BBC's Laura Kuenssberg says it is notable that Harriet Harman focused on detailed questions about the refugee crisis rather than the wider legal, military, and political repercussions of the RAF drone strike. She says this may reflect the fact there is no consensus in Labour on what to do next in Syria and with a new leader to be elected on Saturday, she believed it would have been a mistake to set out too firm a position. 

The final question from DUP MP Nigel Dodds is about threats to the peace process in Northern Ireland. He suggests that the arrest of the Sinn Fein chairman on Wednesday highlights the malign influence of the party - which is in government in Belfast - and the fact it needs to be "dealt with". The PM says he cannot comment on the case but argues that there can be no justification for paramilitary structures remaining in place, saying they "are not wanted and should be disbanded". He ends by urging everyone to rekindle the spirit of the peace process, saying it had a profound effect on him and all those who witnessed the transformation of Northern Ireland in the last 15 years. 

David Cameron said a quarter of Free Schools have been rated outstanding. His figures are correct according to data from OFSTED published at the end of July.

72 out of 136 are good (53% are rated good)

24 out of 136 require improvement (18% require improvement)

6 out of 136 are inadequate (4% are inadequate)

A change of tack as an MP asks about the start of the Rugby World Cup and the economic benefits that could accrue from the world's third largest sporting event. The PM says he believes it will be a compelling contest which he hopes will be won by one of the home nations. 

Tory MP Bernard Jenkin calls for a "full spectrum response" to events in Syria, urging the government to set out its plans, including the possibility of military action. The PM agrees that a "comprehensive approach" is needed to tackle the abuses of the Assad government and Islamic State.

Two questions on the railways, one on plans to phase out elderly Pacer trains in the north of England and another on the electrification of the London to Swansea rail line. The PM uses the question to trumpet the fact that a Hitachi factory in Newton Aycliffe, County Durham, is manufacturing new trains for the network, supporting 700 jobs.
