The Prime Minister gave a warm tribute to interim Labour leader Harriet Harman as she prepared to step down from the role.

Speaking during Prime Ministers Questions, David Cameron said:

I'm sure the whole House will join me in paying tribute to your 28 years of front bench service as it potentially comes to an end this week.

Harriet Harman thanked the Prime Minister for his words, adding: "For me it has been an absolute honour and a privilege to play my part in leading this great party."

Ms Harman plans to return to the backbenches, ending a front bench career which spanned decades of government and opposition.

Left winger Jeremy Corbyn is widely expected to win the Labour crown on Saturday prompting a radical overhaul of his party's front bench team.
