Angela Rayner's constituency home was valued at the exact threshold required to avoid paying Inheritance Tax in what experts said was a 'remarkable coincidence'.

The Deputy Prime Minister is embroiled in a deepening sleaze row over her tax affairs after it was revealed she bought an £800,000 second home on the south coast.

Critics have claimed Ms Rayner avoided £40,000 in stamp duty by telling the taxman that the luxury property in Hove is her main home, while telling the Cabinet Office that her primary residence is her former family home 260 miles away in Greater Manchester.

It has now emerged that her home in her Ashton-under-Lyne constituency - shared with her ex-husband - was valued at £650,000, the highest amount possible before becoming liable for IHT.

The Mail on Sunday revealed that Ms Rayner employed a firm specialising in 'wealth protection' to help dispose of her share of the property.
