Elections to the Wigan council were held on Thursday, 5 May 1988, with one third of the seats up for election as well as an extra vacancy in Beech Hill. Following the previous election, two by-elections had taken place, with the Labour Party successfully defending their seats in Ince and Newtown. This year's election seen an improvement in participation, with all wards fought and five parties contesting in some form, by way of the Greens fielding their first ever slate of four candidates and the return of long-time Communist contender H. Kedward in Leigh Central. Despite this, the number of candidates contesting actually fell by five from the previous year's 64, as the turbulent new merger of the old SDP-Liberal Alliance, Social and Liberal Democrats, fielded just half the number of candidates they'd managed in 1987 and, at 11, the lowest since 1980.
Elections to the Wigan council were held on Thursday, 2 May 1991, with one third scheduled for re-election. Like the last election, this seen a wider variety of party candidates than most previous, but only marginally improved upon the nadir of the year before in terms of candidates, with four wards uncontested, Conservatives fighting just above one half of the seats and the Liberal Democrats just under - although the Lib Dems near doubled last year's total, both were historically disappointing. Minor party participation consisted of three Independent Labour candidates - including a former Beech Hill Labour councillor - two Liberals, a return of an Independent in Hindley Green and one remaining Green - their lowest fielded when participating - in Atherton.
Elections to the Wigan council were held on Thursday, 7 May 1992, with one third of the seats set for re-election. Before the election the Labour Party had successfully retained their seats in three by-elections for the wards of Aspull-Standish, Leigh Central and Norley. The two elections directly preceding 1992's were markedly poor in participation, in contrast this year all wards were fought with the Conservative's and Lib Dem's return to fighting over three quarters of the wards each. Despite this, the election obtained the indisputably worst turnout in the council's near-twenty-year history, at a meagre 23.6%, losing just shy of 12,000 votes from the previous election. The elections were fought one month after the 1992 general election with heavy implications on the results - the most obvious of which is the nationally defeated Labour's loss of 8,000 votes from one year before, and consequently obtaining their worst vote figure in sixteen years. Neither the Conservatives rise - nor the Lib Dem's loss - of around 2,000 each, were significantly removed from recent results or accounted for such a loss, suggesting the slump in turnout were mostly the part of dismayed Labour voters. Seat changes were restricted to two Lib Dems gains from Labour, with one in the Labour-Lib Dem battleground of Aspull-Standish, returning the balance of councillor's in the latter's favour by two to one, and regaining one of their losses in the favourable territory of Langtree.
Elections to the Wigan council were held on Thursday, 5 May 1994, with one third of the seats up for election. Prior to the election, Labour had defended their seats in two by-elections for Abram and Hindley. The election suffered from a mixture of a poor contesting rate and low voter turnout. The number of candidates contesting was just 50, the lowest since 1975, with four wards going unopposed, and Lib Dems back to fighting a half of the seats, and the Conservatives less than two-thirds. The only other opposition standing were three Independent Labour candidates, one of which was the previous - but since deselected - Labour incumbent for the seat being fought in Worsley Mesnes. Voter turnout rose from the previous election's nadir, but at 30.4%, still well below average.
Elections were held on Thursday, 4 May 1995, with one third of the seats set for re-election, with an extra vacancy in Leigh East. Ahead of this election Labour had gained the seat being fought in Beech Hill from the Liberal Democrats, and defended a seat in Worsley Mesnes in by-elections. The major parties marginally increased their number of candidates upon last year's totals, whereas the number of Independent Labour candidates fighting returned to just the incumbent in Hindley. Having been the only party opposing Labour in Atherton, the Independent Labour absence there meant that went uncontested this time round, alongside two of last year's unopposed wards, Ince and Leigh Central. In total unopposed wards were reduced from the previous year's four to three. Turnout fell to 26.4%, the second lowest in the council's history, only surpassing the 1992 nadir.
