Christchurch's new mayor was sworn in at the historic surroundings of Highcliffe Castle and pledged to defend the traditions of the ancient borough.

Cllr Trish Jamieson became the latest custodian of a civic office stretching back more than 700 years.

And her election comes amid uncertain times, as Christchurch looks at a possible merger with Bournemouth and Poole as local councils struggle with harsh financial realities.

Proposing her, Cllr David Jones said it was part of the mayor's role to "preserve, protect and defend" the ancient borough.

"I believe she is very equipped to do that. She is very aware of what makes Christchurch so special."

A senior accountant by profession, Cllr Jamieson took up politics after retiring to Highcliffe. She was first elected to the council in 2004.

Cllr Jones said: "She will fulfil the role as mayor with energy and enthusiasm. I can think of no better person to lead us in what is going to be a very difficult municipal year."

Cllr Lesley Dedman added: "Trish fearlessly stands up for what she believes in and is always calm, professional and determined, a passionate champion of the borough."

The new mayor told guests: "This is a big day for me."

Her charities will be the Stable Family Home Trust, Teenage Cancer Trust and Woofability.

The ceremony heard tributes to former councillor, mayor and Christchurch historian, Mike Hodges, who died two weeks ago.

The Toast to the Ancient Borough was made by Daily Echo editor and head of news, Andy Martin, who said changes to the borough's governance did not have to mean a threat to its history, heritage and values.

Cllr Jamieson will be supported in her year by her mayoral escort, partner Danny Connolly.
