Liberal Democrat leader Nick Clegg made his second campaign visit to Kent - and used the opportunity to raise a glass to the new Royal baby.

His visit on Sunday to the Hush Heath vineyard near Staplehurst was also a bid to give a final boost to the party's efforts to win the Conservative-held Maidstone and Weald seat.

The deputy Prime Minister met activists and candidate Jasper Gerard with just four days to go before polling day.

His visit comes just weeks after an earlier campaign visit to Maidstone's Mid Kent College where he predicted with some confidence the Lib Dems could wrestle the seat away from the Conservatives.

He is the only leader of the three main parties to visit the county during the campaign and his second visit underlines the party's optimism that it could yet pull off an unlikely coup by ousting Conservative candidate Helen Grant.

But before the business side of the visit got underway, he announced a toast to the Duke and Duchess of Cambridge's new baby - born yesterday at 8.34am.

In address to party activists, he said: "You are on the brink of doing something remarkable...the Conservatives are going to lose this seat."

And he took a sideswipe at Mr Cameron and his new style of campaigning to counter critics who say he has lacked passion.

"I do not need to be pumped up or 'bloody lively' to show my conviction," he said.

It wasn't the only birthday being toasted- Mr Gerard's son Freddie turned 11 on Sunday and got to share his celebratory cake with the man who for the last five years has been the country's deputy Prime Minister.

The Conservative party appears to have acknowledged the threat posed by the Lib Dems with the publication of a leaflet admitting the seat is marginal.

Last week, it brought in the former MP Ann Widdecombe to help the campaign - a move seen as further evidence that the party has a fight on its hands.

The full list of candidates standing for Maidstone and the Weald are: Helen Grant (Con), Jasper Gerard (Lib Dem), Dr Paul Hobday (National Health Action Party), Robin Kinrade (Independent), Hannah Patton (Green), Eddie Powell, (Ukip), Allen Simpson (Labour).
