WI: Churchill didn't retire early in his second run as PM?

One thing that I've always wondered is what would happen if Churchill, in his second run as PM didn't retire early, like he never had a stroke or didn't retire afterwards.
Would he have called it quits and not contested the next election, or would he potentially died in office?
Would Nasser even try and seize Suez?
How would the Cold War play out, especially in Hungary?
