Yes- Intense focus on the PM through the media- Powerful image of Margaret Thatcher in tank after Falklands occurred just before her opinion poll increased. No- Parliamentary structure provides more constraints than that of a presidential system- Parliamentary system has the PM as head of the party- Norman Lamont's role in EDM crisis of 1992 hurt the Conservative party as a whole/ EU row in party hurt John Major's chance of re-election in 1997. No- Impact of coalition and minority governments- Lower majority in Parliament makes it more difficult to pass bills through the Commons and leads to greater compromise amongst parties- Conservatives and DUP over social care weakened Theresa May and Conservatives and Lib Dems on scrapping DNA collections on innocent people in 2010-2015 government.
