Euromillions draw: What happened to the UK's biggest lottery winners?

The lucky winner of tonight's £157m Euromillions draw could become the UK's second biggest National Lottery jackpot recipient.

If a single ticket holder scoops the prize it would top the £148m won by Gillian and Adrian Bayford, but it would be just £4m shy of Colin and Christine Weir, the Ayrshire couple who won £161m in July 2011.

The £157m fortune would catapult the winner to 504th position in Britain's rich list  - but as the Bayfords and Weirs would testify, complications can arise when you win such a staggering sum of cash.

The Bayfords, from Haverhill, Suffolk, won £148.6m on the Euromillions ten months ago.

They went public with their win because they thought it would be difficult to give large sums of money away and for people to keep quiet about it.

The couple were said to have flown away in the immediate aftermath of the win, but rather than five-star luxury, they took an easyJet flight to a Scottish caravan park where Mrs Bayford's parents lived.

They were said to have celebrated their win by having Domino's pizza with their two young children.

The couple also reportedly bought a £17,000 Ford Kruga and splashed out on a mansion in the Haverhill area.

Mr Bayford, 41, also ran a music shop in Haverhill, but decided to close the store down in December last year.

He had returned to work at the store despite his huge win, but reportedly closed the store after becoming fed up of people coming inside to beg him for handouts.

The couple have since told how they receive 'around 30 to 40 letters per week' asking for cash - and that they read them all because 'if you don't ask you don't get'.

Colin and Christine Weir became the UK's biggest-ever lottery winners in July 2011, pocketing a mammoth £161m Euromillion jackpot.

The couple, from Largs, Ayrshire, reportedly faced being hounded from their home after their win, having been inundated with hundreds of letters begging for cash.

They were said to have fled to Spain after letters began piling up at their £180,000 three-bedroom home.

There were police patrols outside the Weir's home and the family were said to have gone into hiding soon after landing the prize.

Since then, however, the Weirs have been incredibly generous with their winnings, having contributed to many good causes.

They donated their home to their neighbours after buying a second house, and Mr Weir, a former Scottish TV cameraman, gave £750,000 to his local football team, Largs Thistle.

In November 2012 they also gave almost £30,000 to a mother who asked them to help her cerebral palsy daughter to have revolutionary surgery.

The Weirs wrote a £28,000 cheque to pay for the treatment of three-year-old Skye Swinton.

They also donated a five-figure sum to buy a prosthetic limb for cancer victim Kieran Maxwell, 13.

As well as donations to individual causes, the Weirs gave £900,000 towards a £1.2m sports arena in their home town, and pledged a seven-figure sum to the SNP to help its campaign for independence from the rest of the UK.

The Weirs have spent plenty of their cash on themselves too. They applied for planning permission for a swimming pool and jacuzzi at their £850,000 mansion in Largs.
