Peaches Geldof's older sister misses her ''with all her being''.

The 25-year-old presenter was found dead from a drugs overdose a year ago and her elder sibling Fifi Geldof, 31, has paid tribute on the anniversary of her passing.

Alongside an old school photograph of the two when they were young, Fifi wrote on Instagram: ''A year ago today and I miss you with all of my being.''

Fifi previously posted the same photo on what would have been Peaches' 26th birthday last month.

She wrote at the time: ''Thinking of her on her 26th birthday. Love you, wherever you are.''

It is believed Peaches' family - including widower Thomas Cohen and their sons Astala, two, and Phaedra, 23 months - will celebrate her life with a private memorial service her sister Pixie, 24, has helped organise.

A source said recently: ''Pixie has planned a lot of the memorial service and has made a memory box about Peaches for the boys.

''She wants everyone to light a candle and pick a song that reminds them of Peaches.''

It has also been claimed Thomas and her father, musician Bob Geldof, want to set up a drugs charity in her honour.

The source said: ''Tom and Bob have really bonded over the last year and have a great relationship.

''They are looking at setting up a charitable foundation in Peaches' name to help young people battling drug problems.''
