David Cameron used his speech at this year's Conservative party conference to take a swipe at newly elected Labour leader Jeremy Corbyn today - accusing his opponent of "Britain-hating ideology".
The Prime Minister, who was the closing speaker at the end of the four-day conference in Manchester, delivered a direct warning about the threat posed by his political rival and claimed Corbyn was a "terrorist-sympathiser".
Labour hit back at the PM by suggesting the fact he had used his speech to make "personal attacks" about Corbyn was a "sure sign that he is rattled by the re-energisation of the Labour Party".
The final day of the conference wasn't all about personal sniping though - it was also the platform for the PM to make his keynote speech to party members.
Here is what we learnt:
Key points from Cameron's speech
Vowed to tackle "deep social problems" including extremism, and boost social mobility
Announced "dramatic" planning reforms to increase home ownership as he aims to transform young Britons from "generation rent to generation buy"
Promised to put an end to "passive tolerance" and end discrimination
Claimed he had "no romantic attachment to the European Union"
Defended drone attack that killed two British Islamic State jihadists as an example of "decisive action to keep Britain safe"
Crowd pleasing comments
Cameron's praise for London mayor Boris Johnson earnt him a standing ovation
Joking that he was a 'hooker' while playing rugby at university drew a laugh from the crowd as the PM took a tongue in cheek approach to addressing allegations made in Lord Ashcroft's new book
