At 4ft high and 3.5ft wide, it's one of the biggest trophies in the world of sport.

And it nearly dwarfed these children at a Cambridge school yesterday.

Tennis' Davis Cup has three layers of plaques, on which sits a small cup. It was won by Great Britain last year for the first time since the 1930s, by a team led by Wimbledon and Olympic Champion, Andy Murray.

The team are preparing to take on Argentina in the semi-final in their defence of the title, but the cup is on tour, stopping off at the Leys School in Cambridge, external.

Writer Ross Clark, from Reach near Newmarket, says the "uplifting stories" of the Paralympics are very far from the experience of most people with disabilities. 

He says there is so much to admire in the Paralympics, but it's difficult to watch as it shows the "upper end of ability".  

His 19-year-old daughter Eliza has a severe learning disability and some physical disabilities.

Speaking to BBC Radio Cambridgeshire this morning, Mr Clark said the Games give the impression all disabled people can achieve in sport and the only thing that holds people back is "a lack of ambition, or other people's low expectations".

Speaking about his daughter, Mr Clark said she doesn't understand the competitive element of the events and doesn't have the capability to be inspired by it.

He told the BBC: "When bringing up a child with a learning disability, 90% of challenge is not teaching them new things, it's about dealing with challenging behaviour."

A major study co-led by Cambridge University scientists, external has identified new parts of our genetic make-up that control blood pressure.

The discoveries include DNA changes in three genes that have much larger effects on blood pressure than previously seen. 

High blood pressure or hypertension is a major risk factor for cardiovascular disease and premature death. 

Study author, Dr Joanna Howson from the University of Cambridge, said: "While we have known for a long time that blood pressure is a risk factor for coronary heart disease and stroke, our study has shown that there are common genetic risk factors underlying these conditions."

The Panthers retain a slim chance of reaching the Premier League play-offs following last night's 46-43 win over Rye House. Rathbone admits their recent form has been disappointing.

He told us the last few weeks have "been hard".

"We've come in for a lot of personal abuse from some members of the public," he said.

"I've got to seriously think about the amount of time and effort and finances I put into the club, even though I love Peterborough."

The Peterborough Telegraph reports, external many of its readers heard a loud bang, thought to be a sonic boom, over the area north of Peterborough late this morning.

We've just spoken to the Ministry of Defence, which tells us it has had no reports of anything in the area. 

If we find out more we'll bring it to you.

An empty passenger train that derailed at low speed last night at Welwyn is still causing disruption to services today.

So how do people living on the Cambridgeshire border feel about voting for someone in another county?

Lesley Murfitt, who's a farmer in Littleport, told us: "One politician is much like the other, but I find it very strange to be in a town where I'll be voting for a Norfolk MP but being run by East Cambridgeshire District Council." 

"Are we going to be the poor relation, there to make the numbers up? If you are going to change, change the lot," he said.

Here's what some of our MPs think about the proposed election boundary changes for the next general election in 2020.

Jonathan Djanogly, MP for Huntingdon, external, could lose The Offords and Abbotsley to South Cambridgeshire MP Heidi Allen, but thinks the proposals are sound...

Heidi Allen MP, external has told us that losing Melbourn was a particular shock and that the "really disappointing thing is losing my little bit of the city, Queen Edith's - including Addenbrooke's - which I've really enjoyed representing. It gives me such a different view from what is predominantly rural Cambridgeshire."

When asked what it might mean for people who live in Cambridgeshire but may be represented by a Hertfordshire MP, she said: "It's going to be a little bit confusing from a council point of view.

"People do adjust. There is already quite a draw to Royston and the station. I suspect people won't feel quite such a disconnect."

As we've mentioned, parts of Cambridgeshire's election boundaries could be lost to Norfolk and Hertfordshire under plans published today by the Boundary Commission, external.

But none of our county's constituencies remain unchanged.

Some other proposed changes include:

• Cambridge City to gain Milton and Queen Edith's from South Cambridgeshire. 
• South Cambridgeshire to gain Gransden, The Offords and Fulbourn
• Peterborough to incorporate more of Fletton and Woodstone

The changes are not definite, with a consultation running until 5 December, external.

The final proposals will be published in 2018 and any changes won't come in until the General Election in 2020. 

Despite changes to election boundaries, voters would still remain in the same county and local authority.

Sue Dougan
BBC Local Live

The other big changes proposed by the Boundary Commission are in the south of the county.

Bassingbourn, Melbourn and The Mordens could move out of Heidi Allen's South Cambridgeshire constituency to North East Hertfordshire, which has been held by Conservative Oliver Heald since 1997. 

As well as losing her home village - Steeple Morden - Heidi Allen is also set to lose the Queen Edith's ward in Cambridge to Cambridge City.   

Ms Allen says she'll be "disappointed to lose my little bit of the city".

Nationwide, the proposal is to reduce the number of MP seats from 650 to 600, with the main aim to even out the number of constituents in each area. Each will have about 75,000 voters.

Cambridgeshire has a growing population, with some constituencies currently having 84,000 voters registered.
