TOWN leaders, MPs and councillors have joined thousands across the nation in paying tribute to Prince Philip after he died today aged 99.

Prince Philip has died at the age of 99, Buckingham Palace confirmed this morning.

He was due to celebrate his 100th birthday on June 10, this year.

The Duke of Edinburgh had since returned home after a successful procedure for a pre-existing heart condition.

The news of his death was announced in a statement on Twitter by Royal Family on behalf of the Queen.

It said: “It is with deep sorrow that Her Majesty The Queen has announced the death of her beloved husband, His Royal Highness The Prince Philip, Duke of Edinburgh.

“His Royal Highness passed away peacefully this morning at Windsor Castle.”

The flags at St Helens Town Hall and Earlestown Town Hall are being flown half mast in respect of the Prince, who is the longest serving royal consort.

The Mayor of St Helens Borough Council, Cllr Paul McQuade, led the local tributes, saying: "On behalf of St Helens Borough Council I would like to express condolences to Her Majesty The Queen and members of the Royal Family on the death of HRH The Duke of Edinburgh.

"The Duke visited St Helens in 1977 as part of the Silver Jubilee Celebrations. As a mark of respect we are flying the Town Hall Union Flag at half-mast."

Other town leaders took to social media to share their condolences.
