Sir Tony, who held the keys to Number 10 between 1997 and 2007, is appointed a Knight Companion of the Most Noble Order of the Garter, the oldest and most senior British Order of Chivalry.

The announcement comes as the medical chiefs leading the UK's battle against coronavirus have been recognised in the New Year Honours list.

In any other year, 12-year-old Max Woosey from Devon would have found himself the youngest person ever to be honoured, after raising hundreds of thousands of pounds with his epic camping exploits.

Now Tobias has said he is "chuffed to bits" to be the youngest on record to feature on an honours list, following his series of fundraising challenges during the pandemic lockdowns.

Tobias and Max have given the New Year Honours a distinctly youthful look, helped by an MBE for teenage tennis sensation Emma Raducanu.

There is no official list of those honoured by age, but very few children have received honours since the modern system began.

Paralympic swimming sensation Ellie Simmonds hit the headlines in 2009 when she was made an MBE at the age of 14 and she remains the youngest recipient of that honour.
