It is the Lib Dems who complain most vociferously about Britain’s first-past-the-post voting system.
If Britain had PR (proportional representation) the yellow party would have had 150 MPs in the current Parliament. Instead, they picked up 57 seats.
That may explain why Lib Dems are apostles of electoral reform.
But in 2015 they may appear beneficiaries of the voting system – at least in comparison with Ukip.
That is because most experts predict that the LibDem vote will hold firm in their strongholds such as Colchester, Eastleigh or Twickenham, where they retain a decent ground presence. Senior figures still expect to hold at least 40 seats, even if the party’s share of the vote was to halve from its previous showing of 23 per cent.
