The Sheffield City Council elections take place tomorrow, Thursday 5 May. For the three main parties in Westminster, success or failure in this election will have ramifications at the national level.

The Liberal Democrats

The Lib Dems are currently the largest party in the Council by one seat. If they remain the largest party it would be a huge show of support for Lib Dem leader Clegg in his home city. The deputy prime minister has endured heavy criticism in the press since the Lib Dems joined the Conservatives in the coalition last year and would appreciate a good showing.

On the other hand, if the Lib Dems lose seats in Sheffield it would be a highly symbolic rejection of Clegg. His broken promise on delivering free tuition fees for university students and the government cancellation of a £80 million loan to Sheffield Forgemasters, a significant employer in the city, could cost the Lib Dems.

If the Lib Dems lose seats in Sheffield it could prompt a re-think in national policies. The Lib Dems have been portrayed nationally as having turned their back on their core principles to be part of the coalition. If they are seen to be losing support in a key area such as Sheffield it may result in them reverting to traditional Lib Dem policies.

Labour

Sheffield is particularly interesting for Labour as they have an opportunity to overtake the Lib Dems as the party with the most seats in the Council. Labour success could be seen as a vote of confidence in Ed Miliband’s leadership.

The local council elections across the UK are the first national test of public confidence in Miliband since he became Labour leader last September. Labour won the Barnsley central by-election in March but that was in a safe Labour seat.

Labour will hope to win back seats in traditional working-class Labour strongholds that were lost during the Blair and Brown era. Having previously been public enemy number one because of the opposition to the Iraq war, Labour will want to see this unpopularity transferred to the Lib Dems.

If Labour fail to make gains in Sheffield it could be seen as a rejection of Ed Miliband’s leadership. This could be a sign that the public do not see Labour as a viable alternative to the government.

The Conservatives

The Conservatives currently hold no seats in Sheffield City Council, but they are hopeful of gaining a seat in the Dore and Totley ward. If they gain a seat in Sheffield it could be considered as an acceptance by the public of the measures the government has taken.

If the Conservatives were to take the seat in Dore and Totley it could cause tension with the Lib Dems, their partners in the government coalition. The Dore and Totley seat is currently held by the Lib Dems and is within Lib Dem leader Nick Clegg’s Hallam constituency.

Lib Dem MP Chris Huhne last week accused David Cameron of making personal attacks against Clegg during the AV debate. If the Conservatives were to win a Lib Dem seat within Clegg’s constituency it would add fuel to the fire.

The Conservatives will not be overly perturbed on a national level if they fail to make gains in Sheffield.
