Well, if you accept the Guardian's accuracy, polls have indicated that a clear majority of the British people want to end the restrictions of the Succession Act of 1701 - including the prohibitions against Catholics relating to the throne.
"" The British public overwhelmingly supports an end to the legal ban on Roman Catholics, adopted children and those born to unmarried parents succeeding to the throne, according to an exclusive Guardian/ICM poll on the monarchy published today.
More than 63% of the public agree it is time to end the discrimination inherent in the Act of Settlement 1701, which guarantees the existence of a hereditary monarchy in Britain.
The poll also shows that 60% of British adult voters prefer to see themselves as citizens and only 32% describe themselves as "royal subjects" despite the fact all adults in Britain share that constitutional status. ""

That was a couple of years ago, but I doubt that the sentiment has gotten any weaker.
The Daily Mail seems to agree:
"" The 1701 Act of Settlement bars monarchs and their heirs from becoming or marrying Catholics, a source of anger for Church leaders who have repeatedly called for its repeal.
Under the Act, Mr Phillips will be required to renounce his right to the throne - he is 10th in line at present - or Miss Kelly will have to formally give up her membership of the Church.
Catholic MP John Gummer, tabled a Ten Minute Rule Bill in Parliament earlier this year in a bid to overturn the remaining anti-Catholic legislation.
Mr Gummer said: "It is unacceptable that the part of the Christian church that has more active adherents than any other should be discriminated against in this way."
According to the Act, which discriminates uniquely against Catholics, there is nothing barring a monarch from marrying a Hindu, Muslim or someone from any other faith. ""
