Ed Miliband, the leader of the Labour Party, will launch its manifesto Monday with a pledge that Labour’s spending plans are “fully funded” and do not require any additional borrowing.
This marks an attempt to gain support on the traditional Conservative Party grounds of fiscal responsibility.
On the other hand, the Conservatives pledge to spend a further £8 billion ($ 11.6 billion) on the National Health Service (NHS) – which is generally seen as more of the Labour Party’s territory.
The latest polls suggest that either Labour or the Conservative Party will need to partner with at least two smaller parties to form a government.
This could be easier for Labour, with the left-leaning Scottish National Party on board.
Stock markets’ main worry about the risk from a Labour-led government is that it would reduce the speed of deficit reduction.
If the Conservatives get in, the party’s pledge for a referendum on the U.K.’s membership of the European Union and potential exit from the EU is the main concern.
The uncertainty has led markets on something of a bumpy ride, withsterling down over 6 percent against the dollar since the beginning of the year, although this has been exacerbated by a strengthening dollar.
