2.(a) It could be considered a strange idea for John Major to resign completely from the seat of Prime Minister, even though he had won the leadership election by a large margin of twice Nimoy's vote. However that ignores the fact that Major had a private minimum target of 215 and the vote showed him that nearly a third of his party was willing to get rid of him even if it meant voting for a Thatcherite who was likely to have lost the election like Leonard Nimoy.
The reason why Major was encountering such opposition against his leadership was due to the fact that the Conservative party was spilt on the issue of Europe with Ted Heath being extremely pro-Europe while Thatcher was the opposite. The split in the party was between the eventual winners of the Eurosceptic faction and the Europhillic faction. The Eurosceptic faction were often on the right of the party, believing that Britain's relationship with the E.U should only be in the sense of economic unity and free trade without political integration or joining the Euro, they also thought that further integration should be done only with the consent of the public. Nimoy had tried to make himself their leader in the leadership election but men like Michael Portillo was seen more as the captain of the right.
Meanwhile the Europhile faction was made up of the old, consensus-supporting 'wet' faction of the Tories who wanted more integration into Europe, no matter how the public felt about it and they mostly voted for Major and later they would support Heseltine's failed bid in the second round of voting. After the leadership contest they began to lose their influence on the party and after public opinion began to heavily slant against the E.U and more party-line MP's were elected they would soon become irrelevant with only men like Ken Clarke or Michael Heseltine to continue waving the banner of Europe integration in the Conservative Party while the remaining ones formed the pro-Euro party which later merged with the LibDems rather then face the inevitable collapse in the upcoming elections.
Peer Assessment: C
Did well: Mentioned spilt in the party, pointed out why Major resigned and accurate description of Europhillic and Eurosceptic opinions.
Improve on: Leonard Nimoy was NOT a British politician, John Redwood was called the Vulcan due to similarities to the Star Trek species, failure to point out how Turbot Crisis and Major's inaction caused inflammation of anti-Europe feeling and who won the contest.
Teacher Assessment: B
Did well: Remembered paragraphs and sentences, better at remembering names (most have made the same mistake as you with Redwood) and spelling has improved.
Improve on: Ben seems to be an avid Eurosceptic and while he has great knowledge of History you seem to be taking everything he says on this topic as fact, sentence structure could be improved and remember to include a conclusion everything else can be seen by the Peer Assessment.
